easyui datagrid 表格不让选中(双层嵌套)

代码：

function local(role,region,ip){
    $("#roleList").datagrid({
//        title:'服务器监控列表',
        height:($(window).height())-35,
         iconCls : 'icon-ok',

          pageSize : 15,//默认选择的分页是每页5行数据
          pageList : [ 15,50,100,150 ],//可以选择的分页集合
          nowrap : true,//设置为true，当数据长度超出列宽时将会自动截取
          striped : true,//设置为true将交替显示行背景。
          collapsible : true,//显示可折叠按钮
          toolbar:"#tb",//在添加 增添、删除、修改操作的按钮要用到这个
          url:'report/getAlarmSystem.action',//url调用Action方法
          loadMsg : '数据装载中......',
          singleSelect:true,//为true时只能选择单行
          fitColumns:true,//允许表格自动缩放，以适应父容器
          //sortName : 'xh',//当数据表格初始化时以哪一列来排序
          //sortOrder : 'desc',//定义排序顺序，可以是'asc'或者'desc'（正序或者倒序）。

          pagination : true,//分页
          rownumbers : true,//行数
