How do i get the classname of autofill cells.

How do I get the classnames of those cells that was selected during autofill?

   $('#TestTable').DataTable().on( 'autoFill', function ( e, datatable, cells ) {
                                var x = table.cells('.PublicHoliday');
                                alert(cells[0].className);
                                alert( (cells.length * cells[0].length)+' cells were updated' );
                            } );
