场景：项目上使用到了ant design的table,需要table每列都加上开关，点击开关先弹出提示框，确认之后才可以操作
效果图：

实现过程中需要注意到的点：

1.table都很多列，避免Switch组件渲染问题，可以给组件添加key属性，key唯一

2.修改数据时，视图不会更新的问题，可能是引用类型数据导致的，可以重新换一个地址赋值。

代码如下：

import React, {useEffect, useState} from 'react';

import {Modal , Popconfirm , Switch , Table , Tooltip } from "antd";

const styles = require('./index.less');

const { confirm } = Modal;

// 配置中心
function ConfigCenter(){
  const [tableData,setTableData] = useState([]);

  useEffect(()=>{
    const ary = [
      {id:'xxas',name:'摄像头1#',status:1,delay:true,index:1},
      {id:'232',name:'摄像头1#',status:1,delay:true,index:2},
      {id:'adfa3',name:'摄像头1#',status:1,delay:true,index:3},
      {id:'asdf4',name:'摄像头1#',status:1,delay:false,index:4},
      {id:'safdz',name:'摄像头1#',status:1,delay:true,index:5},
      {id:'gafgc',name:'摄像头1#',status:1,delay:false,index:6},
      {id:'sdfaed',name:'摄像头1#',status:1,delay:true,index:7},
    ]
    setTableData(ary)
  },[])

  const showConfirm = (id,checked)=>{
    confirm({
      title: `是否${checked ? '关闭' : '开启'}延时摄影?`,
      content: '',
      okText: '确认',
      cancelText: '取消',
      style:{padding:'32px 20px'},
      onOk() {
        onChangeSwitch(id,checked);
      },
      onCancel() {
        console.log('Cancel');
      },
    });
  }

  // 停用单个摄像头
  const handleStop = (id)=>{
    console.log(id)
  }

  // 编辑单个摄像头
  const handleEdit = (list)=>{

  }

  // 摄像头置顶
  const handleToTop = (id)=>{

  }

  const onChangeSwitch = (id,checked)=>{
    console.log(id,checked);
    const ary = JSON.parse(JSON.stringify(tableData))
    ary.forEach(item=>{
      if(item.id === id){
        item.delay = !item.delay;
      }
    })
    setTableData(ary);
    console.log(ary)
  }
