Hiding column in jQuery dataTables

Question

I have problem hiding jQuery datatable column. I want that column to retrieve data but I don't want it to be shown on the display page. I want to hide my column no 8 so from CSS I tried hiding it and it gives me collapsable div.

Below is my code for data table and class for hiding is "hideCol".

 var userTable = $('#user').dataTable( {
      "processing": true,
      "serverSide": true,
      "ajax":"admin/getData.php",
      "responsive" : true,
      "lengthMenu": [10, 25],
      "paginationType" : "input",
      columns: [
              { data:'param0'},
              { data: 'param1' },
              { data: 'param2' },
              { data: 'param3' },
              { data: 'param4' },
              { data: 'param5' },
              { data: 'param6' },
              { data: 'param7'},
          ],
      fnRowCallback:function(nRow,aData, iDisplayIndex, iDisplayIndexFull){
        var seenReportedVal =Number($('td:eq(7)', nRow).text());
        $('td:eq(7)', nRow).addClass('hideCol');
        if(seenReportedVal==0)
        {
         $(nRow).addClass('bold');
        }
      },
       "columnDefs": [
                       { "visible": false, "targets": 7 }
                     ],
    });

try using this code

      "processing": true,
      "serverSide": true,
      "ajax":"admin/getData.php",
      "responsive" : true,
      "lengthMenu": [10, 25],
      "paginationType" : "input",
      columns: [

              { data: 'param6' },
              { data: 'param7'},
          ],
       "columnDefs": [
                       { "visible": false, "targets": [7] }
                     ],
    });

You may use visible property of columns. I suggest enclose object attributes with quotes e.g. "columns", "data" or "visible".

"columns": [
          { "data":'param0'},
          { "data": 'param1', "visible": false},
          { "data": 'param2'},
          { "data": 'param3'},
          { "data": 'param4'},
          { "data": 'param5'},
          { "data": 'param6'},
          { "data": 'param7'},
      ]
