话不多说，贴上代码
html代码：

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<link rel="stylesheet" type="text/css" href="../extjs3/resources/css/ext-all.css" rel="external nofollow" />
<script type="text/javascript" src="../extjs3/adapter/ext/ext-base.js"></script>
<script type="text/javascript" src="../extjs3/ext-all.js"></script>
<script type="text/javascript" src="array-grid.js"></script>
<style type="text/css">
.<span style="font-family: Arial, Helvetica, sans-serif;">my_row_class</span><span style="font-family: Arial, Helvetica, sans-serif;">{ background:gray;}</span>
</style>
</head>
<body>
<div id="grid-example"></div>
</body>
</html>

js代码,其中应-----隔开的代码即为关键代码，自己分析吧：

Ext.onReady(function(){
Ext.QuickTips.init();
Ext.state.Manager.setProvider(new Ext.state.CookieProvider());
// sample static data for the store
var myData = [
['3m Co', 71.72, 0.02, 0.03, '9/1 12:00am'],
['3m Co', 71.72, 0.02, 0.03, '9/1 12:00am'],
['Alcoa Inc', 29.01, 0.42, 1.47, '9/1 12:00am'],
['Altria Group Inc', 83.81, 0.28, 0.34, '9/1 12:00am'],
['Altria Group Inc', 83.81, 0.28, 0.34, '9/1 12:00am'],
['Altria Group Inc', 83.81, 0.28, 0.34, '9/1 12:00am'],
['Wal-Mart Stores, Inc.', 45.45, 0.73, 1.63, '9/1 12:00am']
];
/**

function change(val) {
if (val > 0) {
return '<span style="color:green;">' + val + '</span>';
} else if (val < 0) {
return '<span style="color:red;">' + val + '</span>';
}
return val;
}
/**

* @param {Object} val
*/
function pctChange(val) {
if (val > 0) {
return '<span style="color:green;">' + val + '%</span>';
} else if (val < 0) {
return '<span style="color:red;">' + val + '%</span>';
}
return val;
}
// create the data store
var store = new Ext.data.ArrayStore({
fields: [
{name: 'company'},
{name: 'price', type: 'float'},
{name: 'change', type: 'float'},
{name: 'pctChange', type: 'float'},
{name: 'lastChange', type: 'date', dateFormat: 'n/j h:ia'}
]
});
// manually load local data
store.loadData(myData);
// create the Grid
var grid = new Ext.grid.GridPanel({
store: store,
columns: [
{
id :'company',
header : 'Company',
width : 160,

],viewConfig : {forceFit:true
//------------------------------------------------

}
}
//------------------------------------------------
},
stripeRows: true,
autoExpandColumn: 'company',
height: 350,
width: 600,
