如何在Yii中的CGridView中进行较小的文本描述

Question

I have that code in my admin.php i.e. view file in my Yii Project.

<?php $this->widget('zii.widgets.grid.CGridView', array(
    'id'=>'topic-grid',
    'dataProvider'=>$model->search(),
    'filter'=>$model,
    'columns'=>array(
        'id',
        'name',
        'description:html',  // I want to change this
        array(
            'class'=>'CButtonColumn',
        ),
    ),
)); ?>

Actually description:html is showing a lot of text description which is stored in my database.

So my question is that, I want to print just a single line of description here.

So I don't know how to accomplish it.

Any help will be appreciated.

Thanks.

Although hett has given an answer but you can do this also

array(
            'name'=>'description',
            'value'=>array($this,'showFewLines')
        ),

and then in your controller create a function

public function showFewLines($data,$row)
{
$allData=$data->description;
return substr($allData, 0, 40);
}
