<div style="margin:20px 0;"></div>
<table class="easyui-datagrid" title="Aligning Columns in DataGrid" style="width:700px;height:250px"
data-options="singleSelect:true,collapsible:true,url:'datagrid_data1.json',method:'get'">

2、Aligning Columns in DataGrid（数据表格DataGrid的列对齐），运行效果如下图所示。
3、Frozen Columns in DataGrid（在数据表格中冻结的列），You can freeze some columns that can't scroll out of view（你可以冻结一些列让其不能滚动出视图）.
