DataTable Class
A Widget for displaying tabular data. Before feature modules are use()
d,
this class is functionally equivalent to DataTable.Base. However, feature
modules can modify this class in non-destructive ways, expanding the API and
functionality.
This is the primary DataTable class. Out of the box, it provides the ability to dynamically generate an HTML table from a set of column configurations and row data. But feature module inclusion can add table sorting, pagintaion, highlighting, selection, and more.
// The functionality of this table would require additional modules be use()d,
// but the feature APIs are aggregated onto Y.DataTable.
// (Snippet is for illustration. Not all features are available today.)
var table = new Y.DataTable({
columns: [
{ type: 'checkbox', defaultChecked: true },
{ key: 'firstName', sortable: true, resizable: true },
{ key: 'lastName', sortable: true },
{ key: 'role', formatter: toRoleName }
],
data: {
source: 'http://myserver.com/service/json',
type: 'json',
schema: {
resultListLocator: 'results.users',
fields: [
'username',
'firstName',
'lastName',
{ key: 'role', type: 'number' }
]
}
},
recordType: UserModel,
pagedData: {
location: 'footer',
pageSizes: [20, 50, 'all'],
rowsPerPage: 20,
pageLinks: 5
},
editable: true
});
Column Configuration
The column configurations are set in the form of an array of objects, where each object corresponds to a column. For columns populated directly from the row data, a 'key' property is required to bind the column to that property or attribute in the row data.
Not all columns need to relate to row data, nor do all properties or attributes
of the row data need to have a corresponding column. However, only those
columns included in the columns
configuration attribute will be rendered.
Other column configuration properties are supported by the configured
view
, class as well as any features added by plugins or class extensions.
See the description of DataTable.TableView and its subviews
DataTable.HeaderView, DataTable.BodyView, and DataTable.FooterView (and other
DataTable feature classes) to see what column properties they support.
Some examples of column configurations would be:
// Basic
var columns = [{ key: 'firstName' }, { key: 'lastName' }, { key: 'age' }];
// For columns without any additional configuration, strings can be used
var columns = ['firstName', 'lastName', 'age'];
// Multi-row column headers (see DataTable.HeaderView for details)
var columns = [
{
label: 'Name',
children: [
{ key: 'firstName' },
{ key: 'lastName' }
]
},
'age' // mixing and matching objects and strings is ok
];
// Including columns that are not related 1:1 to row data fields/attributes
// (See DataTable.BodyView for details)
var columns = [
{
label: 'Name', // Needed for the column header
formatter: function (o) {
// Fill the column cells with data from firstName and lastName
if (o.data.age > 55) {
o.className += ' senior';
}
return o.data.lastName + ', ' + o.data.firstName;
}
},
'age'
];
// Columns that include feature configurations (for illustration; not all
// features are available today).
var columns = [
{ type: 'checkbox', defaultChecked: true },
{ key: 'firstName', sortable: true, resizable: true, min-width: '300px' },
{ key: 'lastName', sortable: true, resizable: true, min-width: '300px' },
{ key: 'age', emptyCellValue: 'unknown' }
];
Row Data Configuration
The data
configuration attribute is responsible for housing the data objects
that will be rendered as rows. You can provide this information in two ways by default:
- An array of simple objects with key:value pairs
- A ModelList of Base-based class instances (presumably Model subclass instances)
If an array of objects is passed, it will be translated into a ModelList filled
with instances of the class provided to the recordType
attribute. This
attribute can also create a custom Model subclass from an array of field names
or an object of attribute configurations. If no recordType
is provided, one
will be created for you from available information (see _initRecordType
).
Providing either your own ModelList instance for data
, or at least Model
class for recordType
, is the best way to control client-server
synchronization when modifying data on the client side.
The ModelList instance that manages the table's data is available in the data
property on the DataTable instance.
Rendering
Table rendering is a collaborative process between the DataTable and its
configured view
. The DataTable creates an instance of the configured view
(DataTable.TableView by default), and calls its render()
method.
DataTable.TableView, for instance, then creates the <table>
and <caption>
,
then delegates the rendering of the specific sections of the table to subviews,
which can be configured as headerView
, bodyView
, and footerView
.
DataTable.TableView defaults the headerView
to DataTable.HeaderView and the
bodyView
to DataTable.BodyView, but leaves the footerView
unassigned.
Setting any subview to null
will result in that table section not being
rendered.

Methods
_getRecordType
-
val
Returns the Model class of the instance's data
attribute ModelList. If
not set, returns the explicitly configured value.
Parameters:
-
val
ModelThe currently configured value
Returns:
addAttr
-
name
-
config
-
lazy
Adds an attribute with the provided configuration to the host object.
The config argument object supports the following properties:
- value <Any>
- The initial value to set on the attribute
- valueFn <Function | String>
-
A function, which will return the initial value to set on the attribute. This is useful for cases where the attribute configuration is defined statically, but needs to reference the host instance ("this") to obtain an initial value. If both the value and valueFn properties are defined, the value returned by the valueFn has precedence over the value property, unless it returns undefined, in which case the value property is used.
valueFn can also be set to a string, representing the name of the instance method to be used to retrieve the value.
- readOnly <boolean>
- Whether or not the attribute is read only. Attributes having readOnly set to true cannot be modified by invoking the set method.
- writeOnce <boolean> or <string>
-
Whether or not the attribute is "write once". Attributes having writeOnce set to true,
can only have their values set once, be it through the default configuration,
constructor configuration arguments, or by invoking set.
The writeOnce attribute can also be set to the string "initOnly", in which case the attribute can only be set during initialization (when used with Base, this means it can only be set during construction)
- setter <Function | String>
-
The setter function used to massage or normalize the value passed to the set method for the attribute. The value returned by the setter will be the final stored value. Returning Attribute.INVALID_VALUE, from the setter will prevent the value from being stored.
setter can also be set to a string, representing the name of the instance method to be used as the setter function.
- getter <Function | String>
-
The getter function used to massage or normalize the value returned by the get method for the attribute. The value returned by the getter function is the value which will be returned to the user when they invoke get.
getter can also be set to a string, representing the name of the instance method to be used as the getter function.
- validator <Function | String>
-
The validator function invoked prior to setting the stored value. Returning false from the validator function will prevent the value from being stored.
validator can also be set to a string, representing the name of the instance method to be used as the validator function.
- lazyAdd <boolean>
- Whether or not to delay initialization of the attribute until the first call to get/set it. This flag can be used to over-ride lazy initialization on a per attribute basis, when adding multiple attributes through the addAttrs method.
The setter, getter and validator are invoked with the value and name passed in as the first and second arguments, and with the context ("this") set to the host object.
Configuration properties outside of the list mentioned above are considered private properties used internally by attribute, and are not intended for public use.
Parameters:
-
name
StringThe name of the attribute.
-
config
ObjectAn object with attribute configuration property/value pairs, specifying the configuration for the attribute.
NOTE: The configuration object is modified when adding an attribute, so if you need to protect the original values, you will need to merge the object.
-
lazy
Boolean(optional) Whether or not to add this attribute lazily (on the first call to get/set).
Returns:
A reference to the host object.
addAttrs
-
cfgs
-
values
-
lazy
Configures a group of attributes, and sets initial values.
NOTE: This method does not isolate the configuration object by merging/cloning. The caller is responsible for merging/cloning the configuration object if required.
Parameters:
-
cfgs
ObjectAn object with attribute name/configuration pairs.
-
values
ObjectAn object with attribute name/value pairs, defining the initial values to apply. Values defined in the cfgs argument will be over-written by values in this argument unless defined as read only.
-
lazy
BooleanWhether or not to delay the intialization of these attributes until the first call to get/set. Individual attributes can over-ride this behavior by defining a lazyAdd configuration property in their configuration. See addAttr.
Returns:
A reference to the host object.
addColumn
-
config
-
[index]
Adds the column configuration to the DataTable's columns
configuration.
If the index
parameter is supplied, it is injected at that index. If the
table has nested headers, inject a subcolumn by passing an array of indexes
to identify the new column's final location.
The index
parameter is required if adding a nested column.
This method is a convienience method for fetching the DataTable's columns
attribute, updating it, and calling
table.set('columns', _updatedColumnsDefs_)
For example:
// Becomes last column
table.addColumn('name');
// Inserted after the current second column, moving the current third column
// to index 4
table.addColumn({ key: 'price', formatter: currencyFormatter }, 2 );
// Insert a new column in a set of headers three rows deep. The index array
// translates to
// [ 2, -- in the third column's children
// 1, -- in the second child's children
// 3 ] -- as the fourth child column
table.addColumn({ key: 'age', sortable: true }, [ 2, 1, 3 ]);
Parameters:
Returns:
addRow
-
data
-
[config]
-
[callback]
Adds a new record to the DataTable's data
ModelList. Record data can be
an object of field values or an instance of the DataTable's configured
recordType
class.
This relays all parameters to the data
ModelList's add
method.
If a configuration object is passed as a second argument, and that object
has sync: true
set, the underlying Model will be save()
d.
If the DataTable's autoSync
attribute is set to true
, the additional
argument is not needed.
If syncing and the last argument is a function, that function will be used
as a callback to the Model's save()
method.
Parameters:
-
data
ObjectThe data or Model instance for the new record
-
[config]
Object optionalConfiguration to pass along
-
[callback]
Function optionalCallback function for Model's
save()
-
err
Error | NullIf an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be
null
. -
response
AnyThe server's response. This value will be passed to the
parse()
method, which is expected to parse it and return an attribute hash.
-
Returns:
addRows
-
data
-
[config]
-
[callback]
Adds an array of new records to the DataTable's data
ModelList. Record data
can be an array of objects containing field values or an array of instance of
the DataTable's configured recordType
class.
This relays all parameters to the data
ModelList's add
method.
Technically, this is an alias to addRow
, but please use the appropriately
named method for readability.
If a configuration object is passed as a second argument, and that object
has sync: true
set, the underlying Models will be save()
d.
If the DataTable's autoSync
attribute is set to true
, the additional
argument is not needed.
If syncing and the last argument is a function, that function will be used
as a callback to each Model's save()
method.
Parameters:
-
data
Object[]The data or Model instances to add
-
[config]
Object optionalConfiguration to pass along
-
[callback]
Function optionalCallback function for each Model's
save()
-
err
Error | NullIf an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be
null
. -
response
AnyThe server's response. This value will be passed to the
parse()
method, which is expected to parse it and return an attribute hash.
-
Returns:
addTarget
-

Parameters:
-
o
EventTargetthe target to add
after
-
type
-
fn

Returns:
true if an attribute with the given name has been added, false if it hasn't. This method will return true for lazily added attributes.
before
()
Executes the callback before a DOM event, custom event or method. If the first argument is a function, it is assumed the target is a method. For DOM and custom events, this is an alias for Y.on.
For DOM and custom events: type, callback, context, 0-n arguments
For methods: callback, object (method host), methodName, context, 0-n arguments
Returns:
detach handle
blur
()
chainable
Causes the Widget to lose focus by setting the "focused" attribute to "false"
bubble
-
evt
Propagate an event. Requires the event-custom-complex module.
Parameters:

evt
CustomEventthe custom event to propagate
Returns:
the aggregated return value from Event.Custom.fire
delegate
-
type
-
fn
-
spec
-
context
-
args
Pass through to delegate()
called from the contentBox
.

-
args
Any multiple0..n additional arguments to pass on to the callback function. These arguments will be added after the event object.
Returns:
the detach handle
destroy
-
destroyAllNodes
Destroy lifecycle method. Fires the destroy event, prior to invoking destructors for the class hierarchy. Overrides Base's implementation, to support arguments to destroy
Subscribers to the destroy event can invoke preventDefault on the event object, to prevent destruction from proceeding.
Parameters:
-
destroyAllNodes
BooleanIf true, all nodes contained within the Widget are removed and destroyed. Defaults to false due to potentially high run-time cost.
Returns:
A reference to this object
detach
-
type
-
fn
-
context
Detach one or more listeners the from the specified event
Parameters:
-
type
String | ObjectEither the handle to the subscriber or the type of event. If the type is not specified, it will attempt to remove the listener from all hosted events.
-
fn
FunctionThe subscribed function to unsubscribe, if not supplied, all subscribers will be removed.
-
context
ObjectThe custom object passed to subscribe. This is optional, but if supplied will be used to disambiguate multiple listeners that are the same (e.g., you subscribe many object using a function that lives on the prototype)
Returns:
the host
detachAll
-
type
Removes all listeners from the specified event. If the event type is not specified, all listeners from all hosted custom events will be removed.
Parameters:
-
type
StringThe type, or name of the event
disable
()
chainable
Set the Widget's "disabled" attribute to "true".
enable
()
chainable
Set the Widget's "disabled" attribute to "false".
fire
-
type
-
arguments
Fire a custom event by name. The callback functions will be executed from the context specified when the event was created, and with the following parameters.
The first argument is the event type, and any additional arguments are passed to the listeners as parameters. If the first of these is an object literal, and the event is configured to emit an event facade, that object is mixed into the event facade and the facade is provided in place of the original object.
If the custom event object hasn't been created, then the event hasn't been published and it has no subscribers. For performance sake, we immediate exit in this case. This means the event won't bubble, so if the intention is that a bubble target be notified, the event must be published on this object first.
Parameters:
-
type
String | ObjectThe type of the event, or an object that contains a 'type' property.
-
arguments
Object*an arbitrary set of parameters to pass to the handler. If the first of these is an object literal and the event is configured to emit an event facade, the event facade will replace that parameter after the properties the object literal contains are copied to the event facade.
Returns:
True if the whole lifecycle of the event went through, false if at any point the event propagation was halted.
focus
()
chainable
Causes the Widget to receive the focus by setting the "focused" attribute to "true".
get
-
name
Returns the current value of the attribute. If the attribute has been configured with a 'getter' function, this method will delegate to the 'getter' to obtain the value of the attribute.
Parameters:
-
name
StringThe name of the attribute. If the value of the attribute is an Object, dot notation can be used to obtain the value of a property of the object (e.g.
get("x.y.z")
)
Returns:
The value of the attribute
getAttrs
-
attrs
Gets multiple attribute values.
Parameters:
Returns:
An object with attribute name/value pairs.
getCell
-
seed
-
[shift]
Returns the <td>
Node from the given row and column index. Alternately,
the seed
can be a Node. If so, the nearest ancestor cell is returned.
If the seed
is a cell, it is returned. If there is no cell at the given
coordinates, null
is returned.
Optionally, include an offset array or string to return a cell near the
cell identified by the seed
. The offset can be an array containing the
number of rows to shift followed by the number of columns to shift, or one
of "above", "below", "next", or "previous".
// Previous cell in the previous row
var cell = table.getCell(e.target, [-1, -1]);
// Next cell
var cell = table.getCell(e.target, 'next');
var cell = table.getCell(e.taregt, [0, 1];
This is actually just a pass through to the view
instance's method
by the same name.
Parameters:
Returns:
getClassName
-
args
Generate a standard prefixed classname for the Widget, prefixed by the default prefix defined
by the Y.config.classNamePrefix
attribute used by ClassNameManager
and
Widget.NAME.toLowerCase()
(e.g. "yui-widget-xxxxx-yyyyy", based on default values for
the prefix and widget class name).
The instance based version of this method can be used to generate standard prefixed classnames, based on the instances NAME, as opposed to Widget.NAME. This method should be used when you need to use a constant class name across different types instances.
Parameters:
-
args
String* multiple0..n strings which should be concatenated, using the default separator defined by ClassNameManager, to create the class name
getColumn
-
name
Gets the column configuration object for the given key, name, or index. For
nested columns, name
can be an array of indexes, each identifying the index
of that column in the respective parent's "children" array.
If you pass a column object, it will be returned.
For columns with keys, you can also fetch the column with
instance.get('columns.foo')
.
Parameters:
Returns:
the column configuration object
getEvent
-
type
-
prefixed
Returns the custom event of the provided type has been created, a falsy value otherwise
Parameters:
Returns:
the custom event or null
getRecord
-
seed
Returns the Model associated to the record id
, clientId
, or index (not
row index). If none of those yield a Model from the data
ModelList, the
arguments will be passed to the view
instance's getRecord
method
if it has one.
If no Model can be found, null
is returned.
Parameters:
Returns:
getRow
-
id
Returns the <tr>
Node from the given row index, Model, or Model's
clientId
. If the rows haven't been rendered yet, or if the row can't be
found by the input, null
is returned.
This is actually just a pass through to the view
instance's method
by the same name.
Returns:
getSkinName
-
[skinPrefix]
Returns the name of the skin that's currently applied to the widget.
Searches up the Widget's ancestor axis for, by default, a class yui3-skin-(name), and returns the (name) portion. Otherwise, returns null.
This is only really useful after the widget's DOM structure is in the document, either by render or by progressive enhancement.
Parameters:
-
[skinPrefix]
String optionalThe prefix which the implementation uses for the skin ("yui3-skin-" is the default).
NOTE: skinPrefix will be used as part of a regular expression:
new RegExp('\b' + skinPrefix + '(\S+)')
Although an unlikely use case, literal characters which may result in an invalid regular expression should be escaped.
Returns:
The name of the skin, or null, if a matching skin class is not found.
getString
-
key
Helper method to get a specific string value
Parameters:
-
key
String
Returns:
The string
getStrings
-
key
Helper method to get the complete set of strings for the widget
Parameters:
-
key
String
Returns:
The strings
getTargets
()
Returns an array of bubble targets for this object.
Returns:
EventTarget[]
hide
()
chainable
Hides the Widget by setting the "visible" attribute to "false".
init
-
cfg
Init lifecycle method, invoked during construction. Sets up attributes and invokes initializers for the class hierarchy.
Parameters:
-
cfg
ObjectObject with configuration property name/value pairs
Returns:
A reference to this object
isRoot
()
Boolean
Determines if the Widget is the root Widget in the object hierarchy.
Returns:
Boolean indicating if Widget is the root Widget in the object hierarchy.
modifyAttr
-
name
-
config
Updates the configuration of an attribute which has already been added.
The properties which can be modified through this interface are limited to the following subset of attributes, which can be safely modified after a value has already been set on the attribute:
- readOnly;
- writeOnce;
- broadcast; and
- getter.
Note: New attributes cannot be added using this interface. New attributes must be added using addAttr, or an appropriate manner for a class which utilises Attributes (e.g. the ATTRS property in Base).
modifyColumn
-
name
-
config
Updates an existing column definition. Fires the modifyColumn
event.
For example:
// Add a formatter to the existing 'price' column definition
table.modifyColumn('price', { formatter: currencyFormatter });
// Change the label on a header cell in a set of nested headers three rows
// deep. The index array translates to
// [ 2, -- in the third column's children
// 1, -- the second child
// 3 ] -- the fourth child column
table.modifyColumn([2, 1, 3], { label: 'Experience' });
Parameters:
Returns:
modifyRow
-
id
-
data
-
[config]
-
[callback]
Updates an existing record in the DataTable's data
ModelList. The record
can be provided explicitly or targeted by it's id
(see ModelList's
getById
method), clientId
, or index in the ModelList.
After locating the target Model, this relays the all other passed
arguments to the Model's setAttrs
method.
If a configuration object is passed as a second argument, and that object
has sync: true
set, the underlying Model will be save()
d.
If the DataTable's autoSync
attribute is set to true
, the additional
argument is not needed.
If syncing and the last argument is a function, that function will be used
as a callback to the Model's save()
method.
Parameters:
-
id
Object | String | NumberThe Model instance or identifier
-
data
ObjectNew data values for the Model
-
[config]
Object optionalConfiguration to pass along to
setAttrs()
-
[callback]
Function optionalCallback function for Model's
save()
-
err
Error | NullIf an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be
null
. -
response
AnyThe server's response. This value will be passed to the
parse()
method, which is expected to parse it and return an attribute hash.
-
Returns:
moveColumn
-
name
-
index
Moves an existing column to a new location. Fires the moveColumn
event.
The destination index can be a number or array of numbers to place a column header in a nested header row.
Parameters:
Returns:
next
-
circular
Returns the Widget's next sibling.
Parameters:
-
circular
BooleanBoolean indicating if the parent's first child should be returned if the child has no next sibling.
Returns:
Widget instance.
on
-
type
-
fn
-
[context]
-
[arg*]
Subscribe a callback function to a custom event fired by this object or from an object that bubbles its events to this object.
this.on("change", this._onChange, this);
Callback functions for events published with emitFacade = true
will
receive an EventFacade
as the first argument (typically named "e").
These callbacks can then call e.preventDefault()
to disable the
behavior published to that event's defaultFn
. See the EventFacade
API for all available properties and methods. Subscribers to
non-emitFacade
events will receive the arguments passed to fire()
after the event name.
To subscribe to multiple events at once, pass an object as the first argument, where the key:value pairs correspond to the eventName:callback.
this.on({
"attrChange" : this._onAttrChange,
"change" : this._onChange
});
You can also pass an array of event names as the first argument to subscribe to all listed events with the same callback.
this.on([ "change", "attrChange" ], this._onChange);
Returning false
from a callback is supported as an alternative to
calling e.preventDefault(); e.stopPropagation();
. However, it is
recommended to use the event methods whenever possible.
Parameters:
Returns:
A subscription handle capable of detaching that subscription
once
-
type
-
fn
-
[context]
-
[arg*]

removeAttr
-
name
Removes an attribute from the host object
Parameters:

name
StringThe name of the attribute to be removed.
removeColumn
-
name
Removes an existing column. Fires the removeColumn
event.
Parameters:
Returns:
removeRow
-
id
-
[config]
-
[callback]
Removes a record from the DataTable's data
ModelList. The record can be
provided explicitly or targeted by it's id
(see ModelList's getById
method), clientId
, or index in the ModelList.
After locating the target Model, this relays the Model and all other passed
arguments to the data
ModelList's remove
method.
If a configuration object is passed as a second argument, and that object
has sync: true
set, the underlying Model will be destroyed, passing
{ delete: true }
to trigger calling the Model's sync layer.
If the DataTable's autoSync
attribute is set to true
, the additional
argument is not needed.
If syncing and the last argument is a function, that function will be used
as a callback to the Model's destroy()
method.
Parameters:
-
id
Object | String | NumberThe Model instance or identifier
-
[config]
Object optionalConfiguration to pass along
-
[callback]
Function optionalCallback function for Model's
save()
-
err
Error | NullIf an error occurred or validation failed, this parameter will contain the error. If the sync operation succeeded, err will be
null
. -
response
AnyThe server's response. This value will be passed to the
parse()
method, which is expected to parse it and return an attribute hash.
-
Returns:
render
-
parentNode
Establishes the initial DOM for the widget. Invoking this method will lead to the creating of all DOM elements for the widget (or the manipulation of existing DOM elements for the progressive enhancement use case).
This method should only be invoked once for an initialized widget.
It delegates to the widget specific renderer method to do the actual work.
Parameters:
-
parentNode
Object | StringOptional. The Node under which the Widget is to be rendered. This can be a Node instance or a CSS selector string.
If the selector string returns more than one Node, the first node will be used as the parentNode. NOTE: This argument is required if both the boundingBox and contentBox are not currently in the document. If it's not provided, the Widget will be rendered to the body of the current document in this case.
reset
-
name
Resets the attribute (or all attributes) to its initial value, as long as the attribute is not readOnly, or writeOnce.
Parameters:
-
name
StringOptional. The name of the attribute to reset. If omitted, all attributes are reset.
Returns:
A reference to the host object.
scrollTo
-
id
Scrolls a given row or cell into view if the table is scrolling. Pass the
clientId
of a Model from the DataTable's data
ModelList or its row
index to scroll to a row or a [row index, column index] array to scroll to
a cell. Alternately, to scroll to any element contained within the table's
scrolling areas, pass its ID, or the Node itself (though you could just as
well call node.scrollIntoView()
yourself, but hey, whatever).
Parameters:
Returns:
set
-
name
-
value
-
[opts]
Sets the value of an attribute.
Parameters:
-
name
StringThe name of the attribute. If the current value of the attribute is an Object, dot notation can be used to set the value of a property within the object (e.g.

). -
value
AnyThe value to set the attribute to.
-
[opts]
Object optionalOptional data providing the circumstances for the change.
Returns:
A reference to the host object.

-
id
-
width
Assigns the style width of the <col>
representing the column identifed by
id
and updates the column configuration.
Pass the empty string for width
to return a column to auto sizing.
This does not trigger a columnsChange
event today, but I can be convinced
that it should.
Parameters:
Returns:
show
()
chainable
Shows the Widget by setting the "visible" attribute to "true".
showMessage
-

{ username: 'asc' }
. String values are assumed to be ascending.
Example values would be:
-
"username"
- sort by the data'susername
field or thekey
associated to a column with thatname
. -
{ username: "desc" }
- sort byusername
in descending order. Alternately, use values "asc", 1 (same as "asc"), or -1 (same as "desc"). -

Properties
_displayColumns
Object[]
Array of the columns that correspond to those with value cells in the
data rows. Excludes colspan header columns (configured with children
).
ARIA_ACTIONS
Object
static
Mapping of key codes to actions according to the WAI-ARIA suggestion for the Grid Widget.
The key for each entry is a key-code or keyName while the value can be a function that performs the action or a string. If a string, it can either correspond to the name of a method in this module (or any method in a DataTable instance) or the name of an event to fire.
COLGROUP_TEMPLATE
String
The HTML template used to create the table's <colgroup>
.
Default: '<colgroup/>'
CONTENT_TEMPLATE
String
Property defining the markup template for content box. If your Widget doesn't need the dual boundingBox/contentBox structure, set CONTENT_TEMPLATE to null, and contentBox and boundingBox will both point to the same Node.
DEF_PARENT_NODE
String | Node
Default node to render the bounding box to. If not set, will default to the current document body.
KEY_NAMES
Object
static
Mapping of key codes to friendly key names that can be used in the keyActions property and ARIA_ACTIONS property.
It contains aliases for the following keys:
- backspace
- tab
- enter
- esc
- space
- pgup
- pgdown
- end
- home
- left
- up
- right
- down
- f1 .. f12
keyActions
Object
Table of actions to be performed for each key. It is loaded with a clone of ARIA_ACTIONS by default.
The key for each entry is either a key-code or an alias from the
KEY_NAMES table. They can be prefixed with any combination
of the modifier keys alt
, ctrl
, meta
or shift
each followed by a hyphen,
such as "ctrl-shift-up"
(modifiers, if more than one, should appear in alphabetical order).
The value for each entry should be a function or the name of a method in the DataTable instance. The method will receive the original keyboard EventFacade as its only argument.
If the value is a string and it cannot be resolved into a method, it will be assumed to be the name of an event to fire. The listener for that event will receive an EventFacade containing references to the cell that has the focus, the row, column and, unless it is a header row, the record it corresponds to. The second argument will be the original EventFacade for the keyboard event.
Default: Y.DataTable.keyNav.ARIA_ACTIONS
MESSAGE_TEMPLATE
String
Template used to generate the node that will be used to report messages.
Default: <tbody class="{className}"><td class="{contentClass}" colspan="{colspan}"></td></tbody>
SORTABLE_HEADER_TEMPLATE
String
Template for the node that will wrap the header content for sortable columns.
Attributes
autoSync
Boolean
Controls whether addRow
, removeRow
, and modifyRow
should trigger the
underlying Model's sync layer by default.
When true
, it is unnecessary to pass the "sync" configuration property to
those methods to trigger per-operation sync.
Default: `false`
Fires event autoSyncChange
Fires when the value for the configuration attribute autoSync
is
changed. You can listen for the event using the on
method if you
wish to be notified before the attribute's value has changed, or
using the after

attribute supports
it, this class will be used for rendering the contents of the <tbody>
including all data rows.
Similar to view
, the instance of this View will be assigned to the
DataTable instance's body
property.
It is not strictly necessary that the class function assigned here be
a View subclass. It must however have a render()
method.

is
changed. You can listen for the event using the on
method if you
wish to be notified before the attribute's value has changed, or

Parameters:
-
e
EventFacadeAn Event Facade object with the following attribute-specific properties added:
columns
Object[] | String[]
Columns to include in the rendered table.
If omitted, the attributes on the configured recordType
or the first item
in the data
collection will be used as a source.
This attribute takes an array of strings or objects (mixing the two is
fine). Each string or object is considered a column to be rendered.
Strings are converted to objects, so columns: ['first', 'last']
becomes
columns: [{ key: 'first' }, { key: 'last' }]
.
DataTable.Core only concerns itself with a few properties of columns. These properties are:
-
key
- Used to identify the record field/attribute containing content for this column. Also used to create a default Model if norecordType
ordata
are provided during construction. Ifname
is not specified, this is assigned to the_id
property (with added incrementer if the key is used by multiple columns). -
children
- Traversed to initialize nested column objects -
name
- Used in place of, or in addition to, thekey
. Useful for columns that aren't bound to a field/attribute in the record data. This is assigned to the_id
property. -
id
- For backward compatibility. Implementers can specify the id of the header cell. This should be avoided, if possible, to avoid the potential for creating DOM elements with duplicate IDs. -
field
- For backward compatibility. Implementers should usename
. -
_id
- Assigned unique-within-this-instance id for a column. By order of preference, assumes the value ofname
,key
,id
, or_yuid
. This is used by the rendering views as well as feature module as a means to identify a specific column without ambiguity (such as multiple columns using the samekey
. -
_yuid
- Guid stamp assigned to the column object. -
_parent
- Assigned to all child columns, referencing their parent column.
Default: (from `recordType` ATTRS or first item in the `data`)

Parameters:
-
e
EventFacadeAn Event Facade object with the following attribute-specific properties added:
recordType
Function
Model subclass to use as the model

attribute.
If not provided, it will try really hard to figure out what to use. The following attempts will be made to set a default value:
- If the
data
attribute is set with a ModelList instance and itsmodel
property is set, that will be used. - If the
data
attribute is set with a ModelList instance, and itsmodel
property is unset, but it is populated, theATTRS
of the `constructor of the first item will be used. - If the
data
attribute is set with a non-empty array, a Model subclass will be generated using the keys of the first item as itsATTRS
(see the_createRecordClass
method). - If the
columns
attribute is set, a Model subclass will be generated using the columns defined with akey
. This is least desirable because columns can be duplicated or nested in a way that's not parsable. - If neither
data
norcolumns
is set or populated, a change event subscriber will listen for the first to be changed and try all over again.

or delegate to other Views.
It is not strictly necessary that the class function assigned here be
a View subclass. It must however have a render()
method.
When the DataTable is rendered, an instance of this View will be
created and its render()
method called. The View instance will be
assigned to the DataTable instance's view
property.
Default: Y.DataTable.TableView

EventFacadeAn Event Facade object with the following attribute-specific properties added:
Events
addColumn
Fired by the addColumn
method.
destroy
Lifecycle event for the destroy phase, fired prior to destruction. Invoking the preventDefault method on the event object provided to subscribers will prevent destruction from proceeding.
Subscribers to the "after" moment of this event, will be notified after destruction is complete (and as a result cannot prevent destruction).
Event Payload:
-
e
EventFacadeEvent object
init
Lifecycle event for the init phase, fired prior to initialization. Invoking the preventDefault() method on the event object provided to subscribers will prevent initialization from occuring.
Subscribers to the "after" momemt of this event, will be notified after initialization of the object is complete (and therefore cannot prevent initialization).
Event Payload:
-
e
EventFacadeEvent object, with a cfg property which refers to the configuration object passed to the constructor.
modifyColumn
Fired by the modifyColumn
method.
moveColumn
Fired by the moveColumn
method.
removeColumn
Fired by the removeColumn
method.
render
Lifecycle event for the render phase, fired prior to rendering the UI for the widget (prior to invoking the widget's renderer method).
Subscribers to the "on" moment of this event, will be notified before the widget is rendered.
Subscribers to the "after" moment of this event, will be notified after rendering is complete.
Event Payload:
-
e
EventFacadeThe Event Facade
sort
Notifies of an impending sort, either from clicking on a column
header, or from a call to the sort
or toggleSort
method.
The requested sort is available in the sortBy
property of the event.
The default behavior of this event sets the table's sortBy
attribute.
widget:contentUpdate
Notification event, which widget implementations can fire, when they change the content of the widget. This event has no default behavior and cannot be prevented, so the "on" or "after" moments are effectively equivalent (with on listeners being invoked before after listeners).
Event Payload:
