老规矩还是先上图看效果：
这是正确的效果图差不多花了两天的时间去研究这个TreeGrid树形表格，错误原因就是 json 问题，先看返回的json数据：

在这讲解一下easyui TreeGrid的返回json格式的要求（必须严格按照官方的json格式）：
（1）基本json数据格式：
[
{
"m_id": 1,
"m_name": "工作平台",
"m_code": "001",
"m_childrenId": 0,
"m_icon": "fa fa-television fa-2x",

以上是官方要求的json 格式，我返回的json格式有两个bug 第一问题：menu必须是rows 第二问题：menus 必须是children ，
如果你是使用的第一种json数据格式那么menu对象干掉 menus改为children
如果你是用的第二种json格式那么menu必须是rows menus改为children
以上就是我遇到的问题，希望能给同学带来帮助 六一儿童节快乐！
