  <pre><code>$(document).ready(function () {
                  $('#multiServiceJobTable').dataTable().columnFilter({
                       aoColumns: [
                                  null,
                                  {type: "select"},
                                  {type: "select"},
                                  {type: "select"},
                                  {type: "select"},
                                  {type: "select"},
                                  {type: "select"},
                                  {type: "select"}
                              ],
                               aLengthMenu: [
                                            [25, 50, 100, 200, -1],
                                            [25, 50, 100, 200, "All"]
                                            ],
                               iDisplayLength: -1
                  });
  
                  $('#multiServiceJobTable tfoot tr').insertAfter($('#multiServiceJobTable thead tr'));
          });
  </code></pre>
