Disable sorting for a particular column in jQuery DataTables

Question

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

Answer 1

If you already have to hide Some columns, like I hide last name column. I just had to concatenate fname , lname , So i made query but hide that column from front end. The modifications in Disable sorting in such situation are :

    "aoColumnDefs": [
        { 'bSortable': false, 'aTargets': [ 3 ] },
        {
            "targets": [ 4 ],
            "visible": false,
            "searchable": true
        }
    ],

Notice that I had Hiding functionality here

    "columnDefs": [
            {
                "targets": [ 4 ],
                "visible": false,
                "searchable": true
            }
        ],

Then I merged it into "aoColumnDefs"
