yii 2.0 GridView-自定义按钮和链接直接贴代码吧：
<?= GridView::widget([ 'dataPRovider' => $dataProvider, //'filterModel' => $searchModel, 'columns' => [ ['class' => 'yii\grid\SerialColumn'], //显示的字段 //code的值 ['attribute'=>'这是测试code','value'=>function(){return 'abc';}], 'name', 'population', ['class' => 'yii\grid\ActionColumn','header' => '操作',], [ 'label'=>'更多操作', 'format'=>'raw', 'value' => function($data){ $url = "http://www.baidu.com"; return Html::a('添加权限组', $url, ['title' => '审核']); } ] ], ]); ?>
效果如图：
