dcat列表页布局错乱

protected function grid()
{
return Grid::make(new WzOrder(), function (Grid $grid) {
$grid->column(‘id’)->sortable();
$grid->column(‘customer_id’);
$grid->column(‘vin’,’vin编码’);
$grid->column(‘engine_no’,’发动机号’);
$grid->column(‘create_time’);
$grid->filter(function (Grid\Filter $filter) {
$filter->equal(‘id’);

});
});
}

dcat生成列表后页面布局乱了，有哪里设置错误了吗？
