不多说，直接上代码

react-dnd 需要react版本 > 16.6 ,貌似与react.memo方法有关

import React from 'react'
// DragDropContext 类似React的Context
// DragSource 高阶组件 包裹被拖的元素
// DropTarget 高阶组件 包裹被释放的元素 
import {DragDropContext, DragSource, DropTarget} from 'react-dnd';
// HTML5Backend  这个库是必须的，类似于React的合成事件
// 解决浏览器差异，抽象事件操作为可以处理的state
import HTML5Backend from 'react-dnd-html5-backend';
import "./index.css"
