title: Disable Ordering Columns after initialization (init complete) in datatables
body: <p>I would disable order possibility to user after datatables is draw.
  I have a datatable, and I would order a data and remove possibility, for an user, to order data manually.
  How can I do it?</p>
  
  <p>I used below code:</p>
  
  <pre><code>table = $('#tbl-1').DataTable({
              "info": false,
              "searching": true,
              "paging": false,
              "iDisplayLength": 25,
              "lengthMenu": [[10, 25, 50, -1], [10, 25, 50, "Tutti"]],
              "language": {"url": "include/it_IT.txt"},
              "order": [[1,"desc"]],              
              //"ordering": false,
              //"orderFixed": {"pre": [ 1, "desc" ]},                             
               "fnInitComplete": function(oSettings, json) {
                      //alert( 'DataTables has finished its initialisation.' );
                      this.fnFilter("&lt;?php echo $_POST['search'];?&gt;");                        
                    },
              }).on('init.dt', function (e, settings, data) {
                  wrappa(); //after custom function
              });
  </code></pre>
