DT的基础之上再使用jquery的一款插件：treegrid,官网地址：http://maxazan.github.io/jquery-treegrid/
一、使用treegrid，需要以下支持
jquery.min.js+jquery.treegrid.min.js
二、后端提供树状列表格式的集合数据，借助前端的DT的配置控制，来在页面上输出满足treegrid格式要求的html
前台：
1 @using Model
2 @{
3 Layout = null;
4 UserInfo userInfo = null;
5
6 if (ViewData["LoginUser"] != null)
7 {
8 userInfo = ViewData["LoginUser"] as UserInfo;
9 }
10 else
11 {
12 Response.Redirect("/Login/Index");
13 }
14 }

解释说明：
treegrid是通过tr标签上的class内容和tr的位置关系来组织表格中行之间的父子关系和位置关系的，
DT中的配置项：
"rowCallback": function (row, data, displayIndex) {//行定义
if (data.ParentId != "0") {
$(row).attr("class", "text-c treegrid-" + data.PowerId + " treegrid-parent-" + data.ParentId);
} else {
$(row).attr("class", "text-c treegrid-" + data.PowerId);
}
},就是来控制父子关系的。
而后台的List顺序转换，是为了调整好输出的顺序，从而来控制tr之间的位置关系。
通过DT初始化好表格之后，调用
$("#table1").treegrid({
"initialState": 'collapsed',
});即可，绘制好树状表格。
