Answer 2

try this one if you need to make the attribute as label :

[
 'label'=>'' ,
 'header'=>Yii::t('app', 'Sample Number'),
 'attribute'=>'sample_number',  
                  'width'=>'310px',
                  'value' => function ($model) {
                          return Html::a(Html::encode( $model->sample_number), 
                          Url::to(['controller/action', 'sample_number' => $model->sample_number]));
                      },
 'format' => 'raw',     
 'options'=>['class'=>'success','style'=>'font-weight:bold;'],
],
