CGridView and button tiitle

I created a CGridView for categories and with the column with "view", "update" and "delete" buttons I add a column related with articles edit buttons (add article etc) extending the CButtonColumn class.

I want to give at these columns of the table a name, it is possible?


$this->widget('zii.widgets.grid.CGridView', array(

        'dataProvider'=>$dataProvider,

        'columns'=>array(

                'cat_code',

                'cat_name',                

		.......

                array(

                        'class'=>'zii.widgets.grid.CButtonColumn',

                ),

             array(

                         'class'=>'application.components.ButtonColumn',

                ),


array(

    'class'=>'CButtonColumn',

    'header'=>'Column Name',

),
