## 表格構建器渲染輸出 > 說明： 該方法用于表格構建器的渲染輸出。 注意：需在控制器內，使用構建器實例對象調用`assign`方法實現。 > 示例： ```php <?php namespace app\demo\controller; use yunj\Controller; class TableDemo extends Controller { // 方式一 public function demo1(){ $builder=YT('demo1') ->state([11=>'正常',22=>"回收站"]) ->filter(function($state){ $filter=[ 'name'=>['title'=>'姓名'] ];
