同样是listData 为什么写成下面这样就多出一行<optgroup label="0">？

<td><?php echo $form->dropDownList($model,'bumen_bianhao',
array(CHtml::listData(Bumen::model()->findAll(),'bumen_bianhao','bumen' ))); ?>

生成的html
<td><select name="Hetong[bumen_bianhao]" id="Hetong_bumen_bianhao">
<optgroup label="0">
<option value="1">部门1</option>
<option value="2">部门2</option>
<option value="3">部门3</option>
</optgroup>
</select>
</td>

果然是array嵌套引起的,写成这样问题解决了,多谢!
