yii - 使用CGridView列的类显示php警告

Question

I need to apply a CSS class to one CGridView's column and I'm getting a PHP notice error

This is the code

$this->widget('zii.widgets.grid.CGridView', array(
            'htmlOptions'=>array('class'=>'table table-striped table-bordered table-condensed'),
            'dataProvider'=>new CArrayDataProvider( getArray() ),
            'template'=>"{items}",
            'columns'=>array(
                array('name'=>'title', 'header'=>'Title', 'cssClassExpression'=>'span3'),
                array('name'=>'url', 'header'=>'url'),
            ),
        ));

And this is the notice i get:

PHP notice
Use of undefined constant span3 - assumed 'span3'

If i disable PHP notices i correctly see the css class applied to my column.

Does anyone know why this is happening?

Thank you

I fixed the problem using a different syntax for the CGridView column:

array('name'=>'title', 'header'=>'Title', 'htmlOptions'=>array('class'=>'span3')),
