Ext.onReady(function() {   //定义ColumnModel
var cum = new Ext.grid.ColumnModel([
new Ext.grid.RowNumberer(),
{header: '客户ID', dataIndex: 'memid'},

var cumdata = [   //定义数据
['1', 'hello', '男', '1', '2010-05-22'],
['2', 'ASP', '女', '2', '2010-06-07'],
['3', 'JSP', '男', '3', '2011-05-05'],

var store = new Ext.data.Store({

store.load();

var cumgrid = new Ext.grid.GridPanel({
renderTo: 'cumGrid',
store: store,
height: 200,
width: 500,
colModel: cum
});
});
</script>
</head>

<body>
<div id="cumGrid"> </div>
</body>
</html>

3：当删除表格的一行数据时需要注意

Ext.get('remove').on('click', function(){
store.remove(store.getAt(3));  //删除第四行数据
cumgrid.view.refresh();        //重新刷新表格视图
});

一定要重新刷新表格视图
