Extjs GridPanel 加不到 TabPanel里去 那个大哥帮忙下

Question

Ext.onReady(function(){
   var sm=new Ext.grid.CheckboxSelectionModel();
var cm = new Ext.grid.ColumnModel([
new Ext.grid.RowNumberer(),
sm,
{header:'编号',dataIndex:'id',sortable:true},
{header:'名称',dataIndex:'name'},
{header:'描述',dataIndex:'descn'}
]);

var data =[
['1','name1','descn1'],
['2','name2','descn2'],
['3','name3','descn3'],
['4','name4','descn4'],
['5','name5','descn5'],
['6','name6','descn6']
];

var store = new Ext.data.Store({
proxy: new Ext.data.MemoryProxy(data),
reader:new Ext.data.ArrayReader({},[
{name:'id'},
{name:'name'},
{name:'descn'}
])
});
store.load();

var grid = new Ext.grid.GridPanel({
store:store,
cm:cm,
width:450,
height:250,
loadMask:true,
viewConfig:{
forceFit:true
},
bbar: new Ext.PagingToolbar({
pageSize:3,
store:store,
displayInfo:true,
displayMsg:'显示{0}到{1}记录，一共{2}条',
emptyMsg:'没有记录'
}),
autoHeight:true
});




var tabs= new Ext.TabPanel({
renderTo:'grid',
height:100
}); tabs.add({
title:'表格',
closable:true,
layout:'fit',
items:[grid]
});
tabs.add({
title:'aa',
html:'你好'
});
tabs.activate(0);

});效果不是上就是下。。
反正不在TabPanel里边，顺便弱弱的问下，现在用Extjs的公司多吗？

Answer 1

tabs.add({
title:'表格',
xtype:'panel',
closable:true,
layout:'fit',
items:[grid]
});
