kartik-v的DynaGrid的隐藏列数据导出的问题 [ 2.0 版本 ]

DynaGrid 中前端界面上可设置显示隐藏列，我的显示隐藏列功能正常，但是导出数据则未能导出新设置的显示的列

这个是我的view代码

    <?php
	
	        $columns = [

        ['class' => 'kartik\grid\SerialColumn'],

       // ['attribute' => 'id', 'vAlign' => 'middle', 'visible' => false],
        ['attribute' => 'poster', 'vAlign' => 'middle'],
        ['attribute' => 'award', 'vAlign' => 'middle'],
        ['attribute' => 'list_level', 
            'format' => 'raw',
            'filter' =>['县级'=>'县级','市级'=>'市级','省级'=>'省级','国家级'=>'国家级'],
             'filterInputOptions' => ['class' => 'form-control input-sm'],],
        ['attribute' => 'list_grade',
            'format' => 'raw',
            'filter' =>['1'=>'1等奖','2'=>'2等奖','3'=>'3等奖'],
            ],
        ['attribute' => 'list_classify',
