很强大的grid总算登场啦，先来热热身，看下最简单的应用，详细就看注释吧，写的很全面 =-=：

<html>
<body>
<script type="text/javascript">
//页面加载完前执行
Ext.onReady(function()
{
//根据元素id获得页面元素
var page = Ext.get("Page");
//定义json类型对象
var myData = [
['Apple',29.89,0.24,0.81,'9/1 12:00am'],
['Ext',83.81,0.28,0.34,'9/12 12:00am'],

['Yahoo!',29.01,0.42,1.47,'5/22 12:00am']
];
//创建 data store
var ds = new Ext.data.ArrayStore({
//fields可以与具体列绑定,并且定义类型以及格式
fields: [
{name: 'company'},
{name: 'price', type: 'float'},
{name: 'change', type: 'float'},
{name: 'pctChange', type: 'float'},
{name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
]
});
//data store开始加载,当然也可以在grid渲染后加载，具体体现在出现loading条
ds.loadData(myData);
//创建列模型,具体显示列头名称,列样式,能否排序(默认是页面排序,后面有讲到后台排序),dataIndex用来绑定data store具体数据
var columnModel = new Ext.grid.ColumnModel([
{header: "Company", width: 120, sortable: true, dataIndex: 'company'},
{header: "Price", width: 90, sortable: true, dataIndex: 'price'},
{header: "Change", width: 90, sortable: true, dataIndex: 'change'},
{header: "% Change", width: 90, sortable: true, dataIndex: 'pctChange'},
{header: "Last Updated", width: 120, sortable: true, dataIndex: 'lastChange', renderer: Ext.util.Format.dateRenderer('m/d/Y')}
]);
//创建grid对象并且绑定到Page的div层上(众多属性参看api)
var grid = new Ext.grid.GridPanel({renderTo : "Page",height : 300, store : ds, cm: columnModel});
//grid.getSelectionModel().selectFirstRow();
});
</script>
<div id="Page"></div>
