Resetting counter column

[samdamnu]

I need to have the first column of my tables as a counter column (row numbers) that does not get affected by sorting (like in this datatables API example). But inserting that code snippet in the into the fnDrawCallback function breaks the responsive behavior. The columns are hidden alright, but are not expandable anymore.

        fnDrawCallback : function (oSettings) {
            responsiveHelper.respond();


            /* Need to redo the counters if filtered or sorted */
            if ( oSettings.bSorted || oSettings.bFiltered )
            {
                for ( var i=0, iLen=oSettings.aiDisplay.length ; i<iLen ; i++ )
                {
                    $('td:eq(0)', oSettings.aoData[ oSettings.aiDisplay[i] ].nTr ).html( i+1 );
                }
            }

        }
