请问DataTree中 这个要这样解决？

<th data-options="field:'status1',title:'操作',width:100, formatter: fBtn"></th>
        <table data-toggle="topjui-treegrid"
               data-options="id:'menuTg',
               idField:'id',
               treeField:'name',
               url:'/User/List',
               expandUrl:'/User/List?uid={id}',
               fitColumns:true,
               contextMenu:{id:'tgcm'}">
            <thead>
                <tr>
                    <th data-options="field:'uuid',title:'UUID',checkbox:true"></th>
                    <th data-options="field:'id',title:'编号',width:20"></th>
                    <th data-options="field:'name',title:'名称',width:150"></th>
                    <th data-options="field:'status',title:'状态',width:30"></th>
                    <th data-options="field:'status1',title:'操作',width:100, formatter:fBtn"></th>
                </tr>
            </thead>
        </table>


        <script>
            function fBtn(rowIndex, rowData) {
               .....
                var btn = '<a class="layui-btn layui-btn-normal layui-btn-small del" data="' + rowData.id + '">删除</a></div>'
                return  btn;
