当你需要在一个GridView渲染某一个复杂元素的时候（特别是在这种情况下，这是一个小部件），这就需要你在控制器中调用一个动作。例如你给一个GridView的定义这样的一列：

<?php

$this->widget('bootstrap.widgets.TbGridView', array(
    'id' => 'folder-grid',
    'dataProvider' => $model->search($folder_id),
    'template' => "{items}{pager}",
    'rowHtmlOptionsExpression' => 'array("file_id"=>$data->file_id, "file_name"=>rtrim($data->file_name,".".$data->file_ext), "file_ext"=>$data->file_ext)',
    'columns' => array(
        array(
            'selectableRows' => 2,
            'class' => 'CCheckBoxColumn',
            'headerHtmlOptions' => array('width' => '10px'),
            'htmlOptions' => array('class' => 'notopen'),
            'checkBoxHtmlOptions' => array('name' => 'ids[]'),
        ),
        array(
            'name' => 'folder_id',
            'headerHtmlOptions' => array('style' => 'display:none'),
            'htmlOptions' => array('style' => 'display:none;'),
        ),
        array(
            'name' => 'file_name',
            'header' => '文件名',
            'type' => 'raw',
            'headerHtmlOptions' => array('style' => 'width:100%;'),
            'htmlOptions' => array('class' => 'ellipsis'),
            'value' => 'CHtml::openTag("img", array("src" => TFileUtil::getFileTypeIcon($data->file_name,true),"style"=>"margin-right:4px")) . rtrim($data->file_name,".".$data->file_ext)',
        ),
        array(
            'name' => 'more_opt',
            'header' => '',
            'value' => array($this, 'renderButtons'),
            'sortable' => false,
            'htmlOptions' => array('class' => 'more notopen'),
            'headerHtmlOptions' => array('style' => 'width:40px;'),
        ),
        array(
            'name' => 'file_size',
            'header' => '大小',
            'value' => 'TFileUtil::getFileSize($data->file_size)',
            'headerHtmlOptions' => array('style' => 'width:80px;'),
        ),
        array(
            'name' => 'update_time',
            'header' => '修改时间',
            'value' => 'date("Y-m-d H:i:s", $data->update_time)',
            'headerHtmlOptions' => array('style' => 'width:160px;'),
        ),
        array(
            'class' => 'bootstrap.widgets.TbButtonColumn',
            'template' => '{update}{download}{remove}',
            'buttons' => array(
                'update' => array(
                    'label' => '',
                    'options' => array(
                        'class' => 'icon-update td-link-icon',
                        'data-toggle' => 'modal',
                        'data-target' => '#rename_file',
                        'title' => '修改',
                    ),
                    'click' => 'js:function(){ 
                         var $row = $(this).parents("tr");
                         var $column = $(this).parent("td").siblings();
                           var id = $column.eq(0).children("input").val();
                          $("#rename_file #FilePrivate_id").val(id);
                          $("#rename_file #FilePrivate_file_name").val($row.attr("file_name"))
                            .next().text("." + $row.attr("file_ext"));
                       }',
                ),
                'download' => array(
                    'label' => '',
                    'url' => 'Yii::app()->controller->createUrl("/file/private/download",array(
                    "id"=>$data->id,"fileId"=>$data->file_id,"fileName"=>FilePrivate::getFileName($data->id,$data->file_id), "createTime"=>$data->create_time))',
                    'options' => array(
                        'class' => 'download td-link-icon icon-download-2',
                        'title' => '下载',
                    ),
                ),
                'remove' => array(
                    'label' => '',
                    'options' => array(
                        'class' => 'icon-remove td-link-icon',
                        'data-toggle' => 'modal',
                        'data-target' => '#remove',
                        'title' => '删除',
                    ),
                    'click' => 'js:function(){ 
                         var $column = $(this).parent("td").siblings();
                         var id = $column.eq(0).children("input").val();
                          $("#remove #FilePrivate_id").val(id);
                          $("#remove h4").text("删除文件");       
                          $("#remove .note span:eq(1)").text("确定要删除所选的文件吗?");
                          $("#remove #removefiles").hide();
                          $("#remove #removefile").show();
                       }',
                ),
            ),
            'header' => '操作',
            'htmlOptions' => array('style' => 'width:80px;text-align:center;', 'class' => 'notopen'),
            'headerHtmlOptions' => array('style' => 'width:80px;text-align:center;'),
        ),
    )
));
?>

然后在控制器里面这么渲染

/**
     * 显示更多操作的按钮
     */
    public function renderButtons() {
        $this->widget('bootstrap.widgets.TbButtonGroup', array(
            'size' => 'small',
            'buttons' => array(
                array('label' => '', 'items' => array(
                        array('label' => '重命名', 'url' => 'javascript:;', 'linkOptions' => array('id' => 'renameFile')),
                        array('label' => '移动到', 'url' => 'javascript:;', 'linkOptions' => array('id' => 'moveFile')),
                        array('label' => '复制到', 'url' => 'javascript:;', 'linkOptions' => array('id' => 'copyFile'))
                )),
            ),
        ));
    }
