Yii2中GridView设置其中某一行的背景色 [ 2.0 版本 ]

<?= GridView::widget([
    'id' => 'scan-batch-grid',
    'dataProvider' => $dataProvider,
    'rowOptions'=>function($model){
            if($a == $b){
                return ['class' => 'danger'];
            }
    },
]); ?>

或者

<?= GridView::widget([
    'id' => 'scan-batch-grid',
    'dataProvider' => $dataProvider,
    'rowOptions'=>function($model){
            if($a == $b){
                return ['style'=>'color:red;'];
            }
    },
]); ?>
