How to hide if value is false in TbGridView?

Question

MySQL

I'm trying to hide a cell, if the value is different from true, then it is required not to form

$this->widget('bootstrap.widgets.TbGridView', array(
  'id'=>'bs-scenario-grid',
  'dataProvider'=> $dataProvider,
        'columns'   => array(
            [
            'name'  => 'pub',
            'value' => function( $data ) {
                if ($data->pub == 1) {
                    return "true"; 
                } else if($data->pub == 0) { 
                    return "hidden"; 
                }
            }
            ],
        )

Controller -

$dataProvider = new CActiveDataProvider('RoomCat');
        $this->render("admin", array('dataProvider' => $dataProvider));

Answer 1

Hide the table cell, this is something new))) if the value pub == 0 just return an empty string and that's it.
