Yii::使用GridView::widget 定義系統增刪改查按鈕，和自定義按鈕

['class' => 'yii\grid\ActionColumn'], //系統菜單操作
//自定義功能按鈕
[
    'label' =>'更多操作',
    'format'=>'raw',
    'value' => function($data){
        $button = '' ;
        $showUrl      = "/order-change/view?id=".$data->id   ; //查看詳情
        $button .= Html::a('查看詳情', $showUrl, ['title' => '查看詳情']).'<br>' ;

        return $button;
    }
],
