title: How to add a class to the <td> in server-side processing mode
body: <p>When using server-side processing on a DataTable, there is a mechanism to add an ID, class, or <code>data-*</code> attribute to the table row (<code>&lt;tr&gt;</code>) by including the <code>DT_RowId</code>, <code>DT_RowClass</code> or <code>DT_RowData</code> properties, respectively, to the JSON data for each row: <a href="https://datatables.net/examples/server_side/ids.html" rel="nofollow">https://datatables.net/examples/server_side/ids.html</a>.</p>
  
  <p>Is there a similar (or any) mechanism for adding additional markup to the table columns (<code>&lt;td&gt;</code>)?</p>
