【React+Antd】 可展开Table

在antd基础上进行改造，抛弃之前的靠前面+进行展开的方式，在操作列进行点击展开

import { Table } from 'antd';
import React,{useState} from 'react';
import 'antd/dist/antd.css';
import './index.css';
const   APP=()=> {
  const [expandedRowKeys,sexpandedRowKeys]=useState ([]),
  const open = (record) => {
    let expandedRowKey = JSON.parse(
      JSON.stringify(expandedRowKeys)
    ); //一定要深拷贝 不然数组更改视图不更新
    let spliceIndex = expandedRowKey.findIndex((item) => record.id === item);
    if (spliceIndex > -1) {
      expandedRowKey.splice(spliceIndex, 1);
    } else {
      expandedRowKey.push(record.id);
    }
      sexpandedRowKeys(expandedRowKey);
      console.log("expandedRowKeys", expandedRowKeys)
  };
  // render() {
    const columns = [
      { title: 'Name', dataIndex: 'name', key: 'name' },
      { title: 'Age', dataIndex: 'age', key: 'age' },
      { title: 'Address', dataIndex: 'address', key: 'address' },
      {
        title: 'Action',
        dataIndex: '',
        key: 'x',
        render: (record) => <a onClick={() => {open(record)}}>展开</a>,
      },
    ];
    const data = [
      {
        id: 1,
