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