### Configuration Attributes

#### caption `- String`

Value for the CAPTION element.

#### draggableColumns `- Boolean`

True if Columns are draggable to reorder, false otherwise. The Drag & Drop Utility is required to enable this feature. Only top-level and non-nested Columns are draggable. Write once.
Default Value: false

#### generateRequest `- function`

A function used to translate proposed DataTable state info into a value which is then passed to the DataSource's sendRequest method. This function is called to get the DataTable's initial data as well as any data changes or requests such as pagination or sorting. The method is passed two params, an object literal with the state data and a reference to the DataTable.
Default Value: DataTable._generateRequest

#### height `- String`

Table height for scrollable tables. Note: When setting width and height at runtime, please set height first.

#### initialLoad `- Boolean | Object`

Determines whether or not to load data at instantiation. By default, will trigger a sendRequest() to the DataSource and pass in the request defined by initialRequest. If set to false, data will not load at instantiation. Alternatively, implementers who wish to work with a custom payload may pass in an object literal with the following values:

request (MIXED)
  Request value.
argument (MIXED)
  Custom data that will be passed through to the callback function.

Default Value: true

#### initialRequest `- MIXED`

Defines the initial request that gets sent to the DataSource during initialization. Value is ignored if initialLoad is set to any value other than true.
Default Value: null

#### paginated `- object`

Deprecated No longer used, as long as "paginator" value is an instance of Paginator class.

#### paginationEventHandler `- {function|Object}`

For use with Paginator pagination. A handler function that receives the changeRequest event from the configured Paginator. The handler method will be passed these parameters:

1. oState {Object} - an object literal describing the requested pagination state
2. oSelf {DataTable} - The DataTable instance.

For pagination through dynamic or server side data, assign DataTable.handleDataSourcePagination or your own custom handler.
Default Value: DataTable.handleSimplePagination

#### paginator `- {Object|YAHOO.widget.Paginator}`

Stores an instance of Pag, or (for backward compatibility), an object literal of pagination values in the following form:
{ containers:[], // UI container elements
rowsPerPage:500, // 500 rows
currentPage:1, // page one
pageLinks:0, // show all links
pageLinksStart:1, // first link is page 1
dropdownOptions:null, // no dropdown
links: [], // links elements
dropdowns: [] } //dropdown elements
Default Value: null

#### renderLoopSize `- Number`

A value greater than 0 enables DOM rendering of rows to be executed from a non-blocking timeout queue and sets how many rows to be rendered per timeout. Recommended for very large data sets.
Default Value: 0

#### scrollable `- Boolean`

True if primary TBODY should scroll.
Default Value: false

#### selectionMode `- String`

"standard"
  Standard row selection with support for modifier keys to enable multiple selections.
"single"
  Row selection with modifier keys disabled to not allow multiple selections.
