Jquery 将easyui treegrid导出到excel和PDF的方法

我刚刚开始使用jquery和asp.net。Iam将jeasy ui树状网格与asp.net集成（Iam不使用mvc模式），我能够获得示例树状网格。现在我需要将树网格数据导出为excel格式和PDF格式

我参考了堆栈溢出链接

但我帮不了我，有人能帮我吗

Iam使用树网格中提供的以下示例json

[{
"id":1,
"name":"C",
"size":"",
"date":"02/19/2010",
"children":[{
    "id":2,
    "name":"Program Files",
    "size":"120 MB",
    "date":"03/20/2010",
    "children":[{
