vue+elementUI封装一个根据后端变化的动态table(完整代码)

实现了自动生成和插槽两个方式，主要把 el-table 和el-pagination封装在一起

效果图：

使用组件，启用自动生成 :auto="true"

自动生成-编辑 （包括请求已经实现了）新增和删除也是一样

ps:如有额外的按钮可以用插槽实现

查询的时候，只需要多返回下面数据，就可以自动生成列，和对应操作按钮

        <!-- 由后端接口返回的好处：
        接口参数有任何变化，接口名称变更，后端直接更新即可，不用前端修改 ，减少了来回沟通的成本
        组件提供了标准化，完整的基础功能，省去人为复制代码出现bug后修改的时间成本
        省去的基础功能实现的细节，减少了功能细节缺胳膊少腿后期修补的时间成本 -->
