The same story for columns with filtering. 2nd column filtering disable:

$(document).ready(function() {

$('#example').DataTable( {
           initComplete: function () {
            this.api().columns().every( function () {

                var column = this;
                var some = column.index();
                if (column.index() == 1) return;
                var select = $('')
                    .appendTo( $(column.footer()).empty() )
                    .on( 'change', function () {
                        var val = $.fn.dataTable.util.escapeRegex(
                            $(this).val()
                        );

                        column
                            .search( val ? '^'+val+'$' : '', true, false )
                            .draw();
                    } );

                column.data().unique().sort().each( function ( d, j ) {
                    select.append( ''+d+'' )
                } );
            } );
        }})
};
