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!
