基于GridView组件的实现  ~~~ [ 'attribute'=>'create_at', 'format'=>['date', 'php:Y-m-d H:i:s'] ] ~~~ 例子： ~~~ <?= GridView::widget([ 'dataProvider'=>$dataProvider, 'columns'=>[ 'id', 'title', 'content', 'author', 'articleType', [ 'attribute'=>'create_at', 'format'=>['date', 'php:Y-m-d H:i:s'] ], ['class'=>'yii\grid\ActionColumn'] ] ])?> ~~~
