yii gridview button的设置方法

'class' => 'CButtonColumn',           'template' => '{update}{delete}',                 'updateButtonUrl' =>'Yii::app()->createUrl("/customer/editmember1",array("id" => $data->primaryKey))',                 'updateButtonImageUrl'=>Yii::app()->request->baseUrl.'/images/edit.jpg',                 'deleteButtonUrl' =>'Yii::app()->createUrl("/customer/delete",array("id" => $data->primaryKey))',                 'deleteButtonImageUrl'=>Yii::app()->request->baseUrl.'/images/delete.jpg',         ),
