datatables - How to add attribute in TR and TD?

Question

I want to add row using data datatables, and I can do it like this

var table = $('#mytable').DataTable();
table.add.row(['first column', 'second column', 'three column', 'etc']);

What I need is something like this (some attribute in TR and TD tag)

<tr id="someID">
<td>first column</td>
<td>second column</td>
<td>three column</td>
<td id="otherID">etc</td>
</tr>

How I can do it with datatables?

Answer 1

Use createdRow and columns.createdCell options to define a callback function that will be called when TR and TD element are created.

$('#example').dataTable( {
  'createdRow': function( row, data, dataIndex ) {
      $(row).attr('id', 'someID');
  },
  'columnDefs': [
     {
        'targets': 3,
        'createdCell':  function (td, cellData, rowData, row, col) {
           $(td).attr('id', 'otherID'); 
        }
     }
  ]
});

See this example for code and demonstration.
