    //定义数据
    //1.数组
//    var data = [
//        ["1","Troy1","TroyYoung@mwords.com","0","20"],
//        ["2","Troy2","TroyYoung@mwords.com","1","21"],

//    //1.将数据结构和数据组合
//    var store = new  Ext.data.SimpleStore({
//        fields:fields,
//        data:data
//    });
    //2.使用数组数据解析器
//    var store = new Ext.data.Store({
//        data:data,
//        reader:new Ext.data.ArrayReader({id:"id"},fields)
//    });
    //3.使用json数据解析器
//    var store = new Ext.data.Store({
//        data:data,
//        reader:new Ext.data.JsonReader({id:"id",root:"result"},fields)
//    });
    //4.使用jsonStore
    var store = new Ext.data.JsonStore({
        id:"id",
        data:data,
        fields:fields,
        root:"result"
    });

        {header:"Email",dataIndex:"email"},
        {header:"性别",dataIndex:"sex"},
        {header:"年龄",dataIndex:"age"}
        ]);
        
    //定义GridPanel
    var grid = new Ext.grid.GridPanel({
        title:"Grid数据列表显示",
        width:600,
        autoHeight:true,
        cm:cm,
        store:store
    });
    
    //显示数据
    grid.render(Ext.getBody());
