Hey Allan

i'm trying to show loading indicator while loading.

I tried everything that is commented.

the only thing that half worked was the fnInitComplete but i didnt find an event that indicate on the start of the loading.

but didnt worked.

          $('#table').DataTable({
            dom: 'Bfrtip',
            // fnInitComplete : function() {
            //   alert("loading start");
            // },
            // language: {
            //  "processing": "Loading. Please wait..."
            // },
            // "processing": true,
            buttons: ['csv', 'excel', 'pdf'],
            "footerCallback": function(row, data, start, end, display) {
              var api = this.api();
              api.columns('.sum', {
                page: 'current'
              }).every(function(s) {
                if (s != 2) {
                  var sum = this
                    .data()
                    .reduce(function(a, b) {
                      var x = parseFloat(a) || 0;
                      var y = parseFloat(b) || 0;
                      return Number(x + y).toFixed(2);
                    }, 0);
                }
                $(this.footer()).html(sum);
              });
            }
          });

how can i fix this ?

Thanks
