Hi answer is simple from what you think.

<?= GridView::widget([

        'filterModel'  => $searchModel,
        'columns' => [
            ['class' => 'yii\grid\SerialColumn'],

            'id',
            'title',
            //don't use this:
            //'statusId',
            //use this instead:
            [
                'attribute' => 'statusId',
                'filter'    => [ "1"=>"open", "2"=>"in progress", "3"=>"closed" ]
            ],
            ['class' => 'yii\grid\ActionColumn'],

Here's how you need to do this:

[
                'attribute'=>'column_name',
                'label'=>'LABEL OF COLUMN',
                'filter'=>array("first"=>"first","second"=>"second"), // you can read from database directly
                'value' => function ($data) {
                    return $data->column_name;
                }
            ],
