Adding a class to Yii2 CRUD GridView

I've been trying to add a class to the images' column in the CRUD GridView in Yii2. So far, I've managed to display the image, but at its full width and height. I need to add a 'col-md-3' bs class to the image.

This is what I pulled off:

<?= GridView::widget([
'dataProvider' => $dataProvider,
'filterModel' => $searchModel,
'columns' => [
['class' => 'yii\grid\SerialColumn'],

'emp_firstname',
'emp_lastname',
'emp_photo' => [
'format' => 'image',
'attribute' => 'emp_photo',
'value' => 'emp_photo',
'contentOptions' => ['class' => 'col-md-3'],
],

['class' => 'yii\grid\ActionColumn'],
],
]); ?>

Answer

form the column group you can use options http://www.yiiframework.com/doc-2.0/yii-grid-column.html#$options-detail

'emp_photo' => [
        'format' => 'image',
        'attribute' => 'emp_photo',
        'value' => 'emp_photo',
        'options' => ['class' => 'col-md-3'],
    ],

but you should complete the "bootstrap grid" in the other columns
