| 34 | <h1>DataTables example <span>Deferred rendering for speed</span></h1> |
||
| 35 | |||
| 36 | <div class="info"> |
||
| 37 | <p>When working with large data sources, you might seek to improve the speed at which DataTables runs. |
||
| 38 | One method to do this is to make use of the built-in deferred rendering option in DataTables with the |
||
| 39 | <a href="//datatables.net/reference/option/deferRender"><code class="option" title= |
||
| 40 | "DataTables initialisation option">deferRender<span>DT</span></code></a> option.</p> |
||
| 41 | |||
| 42 | <p>When deferred rendering is enabled, rather than having DataTables create all <code class="tag" |
||
| 43 | title="HTML tag">TR</code> and <code class="tag" title="HTML tag">TD</code> nodes required for the |
||
| 44 | table when the data is loaded, DataTables will only create the nodes required for each individual row |
||
| 45 | at the time of that row being drawn on the page (these nodes are then retained in case they are needed |
||
| 46 | again so they aren't created multiple times). This can give a significant performance increase, since a |
||
| 47 | lot less work is done at initialisation time.</p> |
||
| 48 | |||
| 49 | <p>The example below shows DataTables with deferred rendering enabled. For this small example you'll |
||
| 50 | likely notice no difference, but larger tables can benefit significantly from simply enabling this |
||
| 51 | parameter.</p> |
