DataTables server-side processing example
</div>
<h1>Preamble</h1>
<p>There are many ways to get your data into DataTables, and if you are working with seriously large databases, you might want to consider using the server-side options that DataTables provides. Basically all of the paging, filtering, sorting etc that DataTables does can be handed off to a server (or any other data source - Google Gears or Adobe Air for example!) and DataTables is just an events and display module.</p>
<p>The example here shows a very simple display of the CSS data (used in all my other examples), but in this instance coming from the server on each draw. Filtering, multi-column sorting etc all work as you would expect.</p>
<h1>Live example</h1>
<div id="dynamic">
<table cellpadding="0" cellspacing="0" border="0" class="display" id="example">
<thead>
<tr>
<th width="20%">Rendering engine</th>
<th width="25%">Browser</th>
<th width="25%">Platform(s)</th>
<th width="15%">Engine version</th>
<th width="15%">CSS grade</th>
</tr>
</thead>
<tbody>
<tr>
<td colspan="5" class="dataTables_empty">Loading data from server</td>
</tr>
</tbody>
<tfoot>
<tr>
<th>Rendering engine</th>
<th>Browser</th>
<th>Platform(s)</th>
<th>Engine version</th>
<th>CSS grade</th>
</tr>
