  function fillTable(){
     var table = $('#userTable_MainId').DataTable();
     table.clear().draw();
     for(var i=0;i<10;i++){
        var d = [i,"User"+i,"Name"+i,"Last Name"+i,new Date().toISOString().slice(11, 19)];
       table.row.add(d).draw( false );    
     }

  }
  
  $(document).ready(function() {
    $('#userTable_MainId').DataTable();
    fillTable();
  });
