jQWidgets的TreeGrid 心得：

1.下载 jQWidgets 的包，加载到项目。

2.在项目中找到demos/jqxtreegrid/javascript-tree-grid-icons.htm ,打开相应的html,看源代码，修改代码依赖的js文件路径，应用到你的项目中来。

3.构造treegrid 需要，数据源source对象，属性dataType是数据类型，比如json，dataFields是数据对象中有的字段，hierarchy是指定用那个字段来构造父子关系，第一个参数为字段是id，第二字段指向字段reportsTo，比如对象中的reportsTo属性指向另外一个对象id，说明被指对象是其父对象。 localData是json格式的动态数据源，也就是项目中需要的动态数据。

4. $.jqx.dataAdapter（source，{}）；这个对象是可以treegrid加载前进行表格的设置，例如何以单元格中，可以设置图片，可以加载链接，等点击链接后跳转传递数据。

5.$('#treeGrid').jqxTreeGrid({}）；是从页面id为treeGrid的div,里创建treegrid，其中基本的宽度，dataAdapter对象，接下来可设置可否显示图片icon为true，sortable排序，columnGroups表格可拆分设计，pageable分页
