ajax grid 只显示一条数据

[guochunpeng]

Ext.onReady(function() {

var cm = new Ext.grid.ColumnModel([{
header:"id",
dataIndex:"id"
}, {
header:"姓名",
dataIndex:"name"
}, {
header:"email",
dataIndex:"email"
}, {
header:"性别",
dataIndex:"sex"
}, {
header:"年龄",
dataIndex:"age"

}]);
var fileds = ["id","name","email","sex","age"];
var data = [
["1","guochunpeng1","[e-mail]1","0","22"],
["2","guochunpeng2","[e-mail]","1","23"]

];
var store = new Ext.data.SimpleStore({
fields:fileds,
data:data
});
var gird = new Ext.grid.GridPanel({
viewConfig:{forceFit: true},

cm:cm,
store:store
});
gird.render(Ext.getBody());
});

我加进去两条数据，为什么只显示一条数据，请高手指教，我在这里先谢谢了
只显示了这条数据　["1","guochunpeng1","[e-mail]1","0","22"],
第二条没显示

呵呵，我也是自学的，用ext2.0版本的都可以，我用的是ext3.0怎么就不可以啊，用SimpStore　不可以，那用什么可以啊，还请高手指教

是不是grid的高度没设，所以显示不出来？
