tariqnawaz

Hi , I want to disable sorting for my first row in tbody. I have seen all possible example but it did not work for me. I am doing this from last 2 days , so any help will be appreciated. thanks in advance.

javascript

$(document).ready(function() {

    var typeName ='';
    var oTable = $('#table_id1').dataTable({
    //"bPaginate": false,   

    "scrollX" : true,
    "iDisplayLength": 100,
     "lengthMenu": [ 100, 250, 500, 750, 1000 ],

     "columnDefs": [
        {
            "targets": [ 0 ],
            "visible": false
        }
    ],




     initComplete: function () {
            this.api().columns(0).every( function () {
                   var column = this;
                   var select = $('<select id="filterSelect"></select>')
                       .appendTo( $('#type').empty() )
                       .on( 'change', function () {
                           var val = $(this).val();
                           typeName = $(this).val();
                           //console.log(val);
                           fnShowHide( typeName );
                           column.search( val ? '^'+val+'$' : '', true, false )
                               .draw();
                       } );

                   column.data().unique().sort().each( function ( d, j ) {
                       if(d == 'Consistent Performers - Debt funds'){
                                select.append( '<option selected value="'+d+'">'+d+'</option>' )
                                column.search( d ? '^'+d+'$' : '', true, false ).draw();
                                fnShowHide(d);
                           }else{
                                select.append( '<option value="'+d+'">'+d+'</option>' )
                           }

                   } );


               } );


            var self = this;
            var api = this.api();
            api.rows().eq(0).each(function(index) {
                var row = api.row(index);
                //alert("row"+row+"row data"+row.data());
                if(index == 0){

                    var $row_to_persist = $(row.node());
                    var $clone = $row_to_persist .clone();

                    $(self).find('thead:last').append($clone);

                  $total_row.remove();
                    row.remove();
                    //$('#table_id1 thead').append($clone);
                    api.draw();
                }

            }); 

        }



    });
