jsReact Ant Design树形表格的复杂增删改操作js大全

最近因为业务接触了antd,使用antd完成一个复杂的树形表格的显示以及修改。在这其中遇见了不少坑,很多功能antd只写了初步的功能,更为细化的功能只能自己完善。踩过的坑都写在了这里。树形表格的显示树形表格的显示在antd中对于表格的key值有着严格的控制,每一个row都必须有一个独一无二的key值,可以是数字也可以是字符串。这一点和我曾经使用过得iview有着很大的区别。react使用key来代表每一行是为了避免重新渲染的问题,这个优化也在实际的开发中带来了不少的问题。比如新建行时需要自定义新key。下面直接上一下代码及代码效果,这是一个三级的树形表格,且其中包含二级标题。最终效果 colums标题: 简易版标题,随着功能的增加,我们将增加colums的复杂度。
let columns = [
{
title: '题目',
dataIndex: 'text'
},

dataIndex: 'text1'
