datagrid 设置了 showFooter:true 后台 返回数据
 {"footer":[{"goods_fy":"2","goods_nw":"总计:"}],"page":1,"row":20,"rows":[{"create_time":"2018-03-21 11:57:07","goods_code":"HP100129","goods_gw":"2","goods_name":"测试2","goods_nw":"2","goods_sl":"1","goods_yf":"2""},{"create_time":"2018-03-21 11:57:07","goods_code":"HP-100018","goods_gw":"1","goods_name":"大","goods_nw":"1","goods_sl":"1","goods_yf":"1"}],"total":2}
前台界面 不显示footer 是什么原因?
