Disable sorting for a particular column in jQuery DataTables

I am using the jQuery DataTables plugin to sort the table fields. My question is: how do I disable sorting for a particular column? I have tried with the following code, but it did not work:

"aoColumns": [
  { "bSearchable": false },
  null
]   

I have also tried the following code:

"aoColumnDefs": [
  {
    "bSearchable": false,
    "aTargets": [ 1 ]
  }
]

but this still did not produce the desired results.

This is what you're looking for:

$('#example').dataTable( {
      "aoColumnDefs": [
          { 'bSortable': false, 'aTargets': [ 1 ] }
       ]
});

As of DataTables 1.10.5 it is now possible to define initialisation options using HTML5 data-* attributes.

-from DataTables example - HTML5 data-* attributes - table options

So you can use data-orderable="false" on the th of the column you don't want to be sortable. For example, the second column "Avatar" in the table below will not be sortable:

<table id="example" class="display" width="100%" data-page-length="25">
    <thead>
        <tr>
            <th>Name</th>
            <th data-orderable="false">Avatar</th>
            <th>Start date</th>
            <th>Salary</th>
        </tr>
    </thead>
    <tbody>
        <tr>
            <td>Tiger Nixon</td>
            <td><img src="https://www.gravatar.com/avatar/8edcff60cdcca2ad650758fa524d4990?s=64&amp;d=identicon&amp;r=PG" alt="" style="width: 64px; height: 64px; visibility: visible;"></td>
            <td>2011/04/25</td>
            <td>$320,800</td>
        </tr>
        <tr>
            <td>Garrett Winters</td>
            <td><img src="https://www.gravatar.com/avatar/98fe9834dcca2ad650758fa524d4990?s=64&amp;d=identicon&amp;r=PG" alt="" style="width: 64px; height: 64px; visibility: visible;"></td>
            <td>2011/07/25</td>
            <td>$170,750</td>
        </tr>
        ...[ETC]...
    </tbody>
</table>

To make a first column sorting disable, try with the below code in datatables jquery. The null represents the sorting enable here.

$('#example').dataTable( {
  "aoColumns": [
  { "bSortable": false },
  null,
  null,
  null
  ]
} );
