react 实现表格列表拖拽排序的示例

npm install --save react-sortable-hoc
npm install --save array-move

import { SortableHandle } from 'react-sortable-hoc';
import { MenuOutlined } from '@ant-design/icons';

const DragHandle = SortableHandle(() => <MenuOutlined style={{ cursor: 'grab', color: '#999' }} />)


{
            title: '拖动排序',
            dataIndex: 'sort',
            width: 120,
            align: 'center',
            className: 'drag-visible',
            editable: false,
            render: () =>{
                if (editable) return <DragHandle />;
                return <span>禁止拖动</span>
            },
        },

// 在tsx文件中
import React, { useEffect } from 'react';
import { arrayMoveImmutable } from 'array-move';

const Index = () => {
	useEffect(() => {
		let arr = ['a', 'b', 'c']
		let result = arrayMoveImmutable(arr, 1 , 2)
		console.log(result)
		// 结果输入为： [ 'a', 'c', 'b' ]
	})
}

export default Index

import { SortableContainer, SortableElement, SortableHandle } from 'react-sortable-hoc';
import { arrayMoveImmutable } from 'array-move';

// 定义拖拽的table 容器
const DragTableContainer = SortableContainer((props) => <tbody {...props}>)

// 定义 拖拽的 行
const DragTableItem = SortableElement((props) => <tr {...props}>)

// 定义拖拽手柄
const DragHandle = SortableHandle(() => (
	<MenuOutlined title='拖拽排序' />
))

// 表格排序方法
const onSortEnd = ({oldIndex, newIndex}: {oldIndex: number; newIndex: number }) => {
        if (oldIndex !== newIndex) {
            const newData: any[] = arrayMoveImmutable(([] as any[]).concat(dataSource), oldIndex, newIndex).filter((el: any) => !!el);
            handleAllSave(newData) // 父组件传过来的方法，用于更新表格第一列的序号
        }
    }

// 所有可拖拽排序元素的容器
// DragTableContainer 是上面通过 SortableContainer 定义的拖拽的table 容器
// useDragHandle  参数，意思是： 使用行把手拖拽行排序
// disableAutoscroll 参数，禁止自动滚动
// helperClass 参数，可修改拖拽样式
// onSortEnd   `SortableContainer` 提供的一个方法，这个方法可以解构两个形参：`{ oldIndex ,  newIndex }`，一个是拖拽元素的标记，一个是将要放的地方的标记，用于表格拖拽排序

const DraggableContainer = (props: any) => <DragTableContainer useDragHandle disableAutoscroll helperClass="row-dragging" onSortEnd={onSortEnd} {...props}/>


// 定义 拖拽的 行

// DraggableBodyRow  返回的是由 SortableItem  包裹的每一行元素

const DraggableBodyRow = ({ className, style, ...restProps}: any) => {
    const index = dataSource.findIndex((x: any) => x.orderNum === restProps['data-row-key']);
    return (<SortableItem index={index} {...restProps} />)
}
