__** 前端就是没有数据显示**__
这是转换后字符串型的josn数据
{"rows":[{"already_invoiceMoney":0},{"already_invoiceMoney":0},{"already_invoiceMoney":0}],"total":64}
field的字段名要与json数据的字段名对应
不要一次性写那么多字段，你就写一个字段看出的来不
easyui框架正确导入没有，页头显示出来了吗？要先导入jquery再导入easyui，循序不能错
自己f12打开浏览器开发工具看js是否报错
看后台值获取了没，再看传到前台没，如果传到了没有，看jar包导的对不，字段名是否对的上。
