new Ext.grid.Column({header: "品牌图标",dataIndex:'',align:'center',width:100,renderer:function(value, metaData, record){
return "<img src='BinaryServlet?action=get_brand&brand_id="+record.get('BRAND_ID')+"&ts="+new Date().toString()+"' width='90px' height='36px'/>";
}}),
上面代码是我朋友写的
[color=red]关键是设置Column的
align:'center' 属性[/color]
