Preamble

The two default pagination styles that DataTables comes with are great for basic tables, but you might want to add extra customisation or a bit of 'glitz'. This plug-in will scroll the table in an animated style.

Initialisation code

/* Time between each scrolling frame */
$.fn.dataTableExt.oPagination.iTweenTime = 100;

$.fn.dataTableExt.oPagination.scrolling = {
	"fnInit": function ( oSettings, nPaging, fnCallbackDraw )

		 * usful for automation - particularly testing
		 */
