React使用antd Table生成层级多选组件

一、需求

　　用户对不同的应用需要有不同的权限，用户一般和角色关联在一起，新建角色的时候会选择该角色对应的应用，然后对应用分配权限。于是写了一种实现的方式。首先应用是一个二级树，一级表示的是应用分组，二级表示的是应用，这是table的最左边的数据。然后是按钮的数据，这里显示在table的头部。

二、效果图如下

　　

 三、具体代码

　　1.RoleApplicationTable.js

　　js实现的Map工具类。

 四、需求变更

　　功能虽然完成了，但是总是避免不了需求的变更。要求选择左边应用对应的checkbox时，不在操作该应用对应的按钮的checkbox,也就是整个行不是全选了。应用对应的checkbox用来进行删除操作。

五、心得体会

　　最近使用react + redux + webpack进行web开发，感觉进步很快，已经熟悉了基本的流程。后续要研究一下webpack。
