easyui dataguid subgrid 子表

用easyui 的dataguid打造的界面，主要是学习了subgrid的试水，挺好用的 

下面是js,  关键的一段，主要是要注意view: detailview下面开始的就是子表的一段，页面我就不给了，很简单的，有<table id="data_result"></table>就行了，不过一定要引入

datagrid-detailview.js ，点击小“+”会触发onExpandRow，接下来的就好理解了，$('#data_result').datagrid('fixDetailRowHeight',index); 这个很重要，是用来保持弹出的子表高度和

附表的行数高度一致，否则表格会变形覆盖
