使用自定义元素,我们可以集成 react-dnd 来实现拖拽排序。
en-US
By using components
, we can integrate table with react-dnd to implement drag sorting function.
import { Table } from 'antd';
import type { ColumnsType } from 'antd/es/table';
import update from 'immutability-helper';
import React, { useCallback, useRef, useState } from 'react';
import { DndProvider, useDrag, useDrop } from 'react-dnd';
import { HTML5Backend } from 'react-dnd-html5-backend';
interface DataType {
key: string;
name: string;
age: number;
address: string;
}
interface DraggableBodyRowProps extends React.HTMLAttributes<HTMLTableRowElement> {
index: number;
moveRow: (dragIndex: number, hoverIndex: number) => void;
}
const type = 'DraggableBodyRow';
const DraggableBodyRow = ({
index,
moveRow,
className,
style,
...restProps
}: DraggableBodyRowProps) => {
const ref = useRef<HTMLTableRowElement>(null);
const [{ isOver, dropClassName }, drop] = useDrop({
accept: type,
collect: monitor => {
const { index: dragIndex } = monitor.getItem() || {};
if (dragIndex === index) {
return {};
}
return {
isOver: monitor.isOver(),
dropClassName: dragIndex < index ? ' drop-over-downward' : ' drop-over-upward',
};
},
drop: (item: { index: number }) => {
moveRow(item.index, index);
},
});
const [, drag] = useDrag({
type,
item: { index },
collect: monitor => ({
isDragging: monitor.isDragging(),
}),
});
drop(drag(ref));
return (
<tr
ref={ref}
className={`${className}${isOver ? dropClassName : ''}`}
style={{ cursor: 'move', ...style }}
{...restProps}
/>
);

const columns: ColumnsType<DataType> = [

dataIndex: 'age',

const App: React.FC = () => {
const [data, setData] = useState([

const moveRow = useCallback(

const dragRow = data[dragIndex];
setData(
update(data, {
$splice: [
[dragIndex, 1],
[hoverIndex, 0, dragRow],

[data],

return (

<Table

components={components}
onRow={(_, index) => {
const attr = {
index,
moveRow,

return attr as React.HTMLAttributes<any>;
}}

</DndProvider>
);
