jQuery EasyUI Tree Menu - Create Complex TreeGrid
The TreeGrid can display a multi-column and complex data spreadsheet in a limited space. This tutorial will demonstrate how to arrange table data in a split grid and multi-row headers to organize common data.
Create TreeGrid
<table title="Complex TreeGrid" class="easyui-treegrid" style="width:550px;height:250px"
url="data/treegrid2_data.json"
rownumbers="true" showFooter="true"
idField="id" treeField="region">
<thead frozen="true">
<tr>
<th field="region" width="150">Region</th>
</tr>
</thead>
<thead>
<tr>
<th colspan="4">2009</th>
<th colspan="4">2010</th>
</tr>
<tr>
<th field="f1" width="50" align="right">1st qrt.</th>
<th field="f2" width="50" align="right">2nd qrt.</th>
<th field="f3" width="50" align="right">3rd qrt.</th>
<th field="f4" width="50" align="right">4th qrt.</th>
<th field="f5" width="50" align="right">1st qrt.</th>
<th field="f6" width="50" align="right">2nd qrt.</th>
<th field="f7" width="50" align="right">3rd qrt.</th>
<th field="f8" width="50" align="right">4th qrt.</th>
</tr>
</thead>
</table>
As you can see, the usage of TreeGrid is the same as DataGrid. Use the 'frozen' attribute to define frozen columns, and the 'colspan' and 'rowspan' attributes to define multi-row headers.
