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" /><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']    ];    /**     * Custom function used for column renderer     * @param {Object} val     */    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;    }    /**     * Custom function used for column renderer     * @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,                 sortable : true,                 dataIndex: 'company'            },            {                header   : 'Price',                 width    : 75,                 sortable : true,                 renderer : 'usMoney',                 dataIndex: 'price'            },            {                header   : 'Change',                 width    : 75,                 sortable : true,                 renderer : change,                 dataIndex: 'change'            },            {                header   : '% Change',                 width    : 75,                 sortable : true,                 renderer : pctChange,                 dataIndex: 'pctChange'            },            {                header   : 'Last Updated',                 width    : 85,                 sortable : true,                 renderer : Ext.util.Format.dateRenderer('m/d/Y'),                 dataIndex: 'lastChange'            }        ],viewConfig : {forceFit:true       //------------------------------------------------        ,getRowClass : function(record,rowIndex,rowParams,store){         if("3m Co"==record.get('company')){        return 'my_row_class';        }        }       //------------------------------------------------    },        stripeRows: true,        autoExpandColumn: 'company',        height: 350,        width: 600,        title: 'Array Grid',        // config options for stateful behavior        stateful: true,        stateId: 'grid'    });    // render the grid to the specified div in the page    grid.render('grid-example');});
