react antd design pro 的protable的另类使用方法。

protable中antd design的一个强大的组件。具体介绍

https://protable.ant.design/

简单的表可以通过大进行快速处理。相当方便。

 

但用完以后发现，跟实际需求相差还是很大的。有些字段是临时生成的。在表里是没有的。翻了官网，硬是没有找到相关解决办法。突发一想，想到以下解决办法。

以时间字段为例。数据库里，只有createtime字段。有些状态值，是根据其余字段计算出来，在数据库里也是没有值的。但页面需要展示开始和结束时间等等，要如何处理。。

看后台文件如何处理方法

        //print_r($obj->getLastSql());
        echo json_encode($list);

    }

}

走读一下代码就知道其中逻辑。原理就是我们通过接口文件造临时的数据类型的参数，让他符合protable的条件，让其自动生成一些参数。这样的话就没啥问题，可以继续用protable。让后台代码，迁就与前端的组件实现，尽可能的减少前端代码

做完前后端才发现，前后端配合还是可以减少工作量的。
