Antd+React+react-resizable实现表格拖拽功能

news 2025/7/29 1:03:19

1、先看效果

2、环境准备

在package.json 引入相关的依赖

  "dependencies": {"antd": "^5.4.0","react-resizable": "^3.0.4",},"devDependencies": {"@types/react": "^18.0.33","@types/react-resizable": "^3.0.1",}

3、功能实现

一、拖拽组件实现

1、导入所需组件：在你的代码文件中导入所需的组件：

import { Resizable, ResizableProps } from 'react-resizable';

2、创建可调整大小的列组件：为了实现表格拖拽功能，你需要为每一列创建一个可调整大小的组件。在每个表格列的头部，使用Resizable组件来包裹列的内容：

/*** 公共组件：实现拖拽*/
import { isNumber } from 'lodash';
import { StyleHTMLAttributes } from 'react';
import { Resizable, ResizableProps } from 'react-resizable';type ResizableTitleProps = ResizableProps & {resizable?: boolean;style: StyleHTMLAttributes<any>;
};const ResizableTitle = (props: ResizableTitleProps) => {const { onResize, width, resizable, ...restProps } = props;if (!width || !resizable) {return <th {...restProps} />;}let resizeWidth: any = width;if (!isNumber(resizeWidth)) {resizeWidth = Number(resizeWidth.replace('px', ''));}return (<Resizablewidth={resizeWidth}height={0}handle={<spanclassName="react-resizable-handle"onClick={(e) => {e.stopPropagation();}}/>}onResize={onResize}draggableOpts={{ enableUserSelectHack: true }}// maxConstraints={[800, 800]}><th{...restProps}style={{...restProps?.style,width: `${resizeWidth}px`,borderRight: '1px solid rgba(2, 9, 23, 70%)',}}/></Resizable>);
};export default ResizableTitle;

在上面的代码中，我们使用Resizable组件来包裹了列的内容。handle属性定义了列的调整大小的手柄样式，你可以根据需要自定义。draggableOpts属性用于配置调整大小的选项。

二、在antd写入tab，并引用该拖拽组件

1、在table的components属性中，引入该拖拽组件

 <Table...{...(isResizable? {components: {header: {cell: ResizableTitle, // 动态拖拽设置列宽},},}: {})}columns={getColumns(currentColumns)}{...props}/>

2、对每一列的onHeaderCell都加上拖拽的属性resizable，控制该列是否可拖拽，配置onResize的回调方法

  const getColumns = (columns: any) => {return (columns || []).map((col: any, idx: number) => {return {...col,onHeaderCell: (column: any) => ({width: column.width || 100,resizable: isResizable && !column?.fixed,onResize: handleResize(idx, col.dataIndex as string),}),};});};

3、拖拽后更新表格的列宽

// 拖拽后更新表格宽度const handleResize =(index: number, colDataIndex?: string) =>(e: any, { size }: { size: { width: number } }) => {if (!colDataIndex) {return;}setCurrentColumns((pre) => {let temp = [...pre];temp[index] = {...temp[index],width: size.width < 50 ? 50 : size.width,};computedWidth(temp);return temp;});};

4、具体实现如下：

import { Table } from 'antd';
import clsx from 'clsx';
import React, { useEffect, useState } from 'react';
import ResizableTitle from './ResizableTitle';
import styles from './index.less';export interface ListTableProps {className?: any;rowClassName?: any;dimension?: number;columns?: any;dataSource?: any;pagination?: any;scroll?: object;virtual?: boolean;rowKey?: any;isShowScrollX?: boolean;vid?: string;isResizable?: boolean; //是否可退拽onChange?: (pagination: any, filters: any, sorter: any) => void;
}// 暂无数据组件
const NoDataComponent = () => {return (<div className={clsx(['h-[250px]', 'flex justify-center items-center'])}><divclassName={clsx(['w-[76px] h-[94px]','bg-[url("/images/no-data.svg")] bg-no-repeat',])}/></div>);
};const ListTable: React.FC<ListTableProps> = ({className,rowClassName = () => '',onChange,dataSource,isShowScrollX,defaultFixedNode,columns: initCols,isResizable,vid = 'resize_table',...props
}) => {const [currentColumns, setCurrentColumns] = useState([]);const [leftRightNodeIsFixed, setLeftRightNodeIsFixe] =useState(defaultFixedNode); // 左右节点是否固定useEffect(() => {setCurrentColumns(initCols);}, [initCols]);useEffect(() => {setCurrentColumns(initCols);}, [initCols]);// 计算宽度，当出现底部滚动条时，最左最右节点固定const computedWidth = (columns: any) => {const widthAll =document.getElementsByClassName('ant-table-body')?.[0]?.clientWidth;const currentTabWidth = (columns || []).reduce((pre: number, cur: any) => {return Number(pre) + (Number(cur?.width) || 0);}, 0);setLeftRightNodeIsFixe(currentTabWidth > widthAll);};
// 拖拽后更新表格宽度const handleResize =(index: number, colDataIndex?: string) =>(e: any, { size }: { size: { width: number } }) => {if (!colDataIndex) {return;}setCurrentColumns((pre) => {let temp = [...pre];temp[index] = {...temp[index],width: size.width < 50 ? 50 : size.width,};computedWidth(temp);return temp;});};const getColumns = (columns: any) => {return (columns || []).map((col: any, idx: number) => {return {...col,onHeaderCell: (column: any) => ({width: column.width || 100,resizable: isResizable && !column?.fixed,onResize: handleResize(idx, col.dataIndex as string),}),};});};return (<TablerowClassName={(record, index) => {return rowClassName(record, index);}}locale={{ emptyText: <NoDataComponent /> }}{...(isResizable? {components: {header: {cell: ResizableTitle, // 动态拖拽设置列宽},},}: {})}columns={getColumns(currentColumns)}onChange={onChange}dataSource={dataSource}{...props}/>);
};export default ListTable;
