这里是一个老例子哈

建立一个xml文件：plants.xml

<?xml version="1.0" encoding="utf-8"?>
<catalog>
<plant>
    <common>Bloodroot</common>
    <botanical>Sanguinaria canadensis</botanical>
    <zone>4</zone>
    <light>Mostly Shady</light>
    <price>2.44</price>
    <availability>03/15/2006</availability>
    <indoor>true</indoor>
</plant>
<plant>
    <common>Columbine</common>
    <botanical>Aquilegia canadensis</botanical>
    <zone>3</zone>
    <light>Mostly Shady</light>
    <price>9.37</price>
    <availability>03/06/2006</availability>
    <indoor>true</indoor>
</plant>
</catalog>

建立js:load.js

       dataIndex: 'indoor',
       width: 55
    });

    // dataIndex maps the column to the specific data field in
    // the data store (created below)
