react实现table可拖拽表头

安装依赖

yarn add react-resizable 
yarn add react-jss

resizableTitle / index.tsx

import { createUseStyles } from 'react-jss';
import { Resizable } from 'react-resizable';

const useResizableTitleStyles = createUseStyles({
  resizableHandle : {
    position: 'absolute',
    right: '-5px',
    bottom: 0,
    zIndex: 1,
    width: '10px',
    height: '100%',
    cursor: 'col-resize'
  }
});
// 表头拖拽组件
export const ResizableTitle = ({ onResize, width, isNotResizable, ...restProps }) => {
  const classes = useResizableTitleStyles();
  // 新增处理函数，用于阻止事件冒泡
  const stopPropagation = (event) => event.stopPropagation();
  // isNotResizable 或者 没有宽度 不可拖拽
  console.log('isNotResizable',isNotResizable, width, 'restProps', restProps);
  
  if (!width || isNotResizable) { return (<th {...restProps} />) };
  return (
    <Resizable
      width={width}
      height={0}
      handle={
        <span className={classes.resizableHandle} onClick={stopPropagation} />
      }
      onResize={onResize}
      draggableOpts={{ enableUserSelectHack: false }}
    >
      <th {...restProps} style={{ ...restProps?.style, userSelect: 'none' }} />
    </Resizable>
  );
};

drapTable.tsx

import type { TableProps } from 'antd';
import { Table } from 'antd';
import { useState, useMemo, useEffect, useCallback } from 'react';
import type { ColumnType } from 'antd/lib/table';
import { ResizableTitle } from './resizableTitle/index';
import { createUseStyles } from 'react-jss';

interface TableStylesProps {
  paddingVertical?: number;
  paddingHorizontal?: number;
}
// 设置table的 cell里面的 padding
const useTableStyles = createUseStyles({
  base_table_com: {
    '& .ant-table-thead > tr > th, & .ant-table-tbody > tr > td, & .ant-table tfoot > tr > th, & .ant-table tfoot > tr > td':
      {
        padding: (cProps: TableStylesProps) =>
          `${cProps.paddingVertical ?? 10}px ${
            cProps.paddingHorizontal ?? 12
          }px`,
      },
  },
});

export const DragTable = <RecordType extends Record<string, any> = any>(
  props: ICommonTableProps<RecordType>,
) => {
  const {
    showTotalNum = true,
    pagination,
    hidePagination,
    paddingVertical,
    paddingHorizontal,
  } = props;
  const [tablePagination, setTablePagination] = useState<any>(pagination);
  const classes = useTableStyles({ paddingVertical, paddingHorizontal });

  const { columns } = props;

  // 设置可拖拽的表头
  const [rescolumns, setResColumns] = useState<ColumnType<any>[]>(
    columns.filter((column) => !column.hide) || [],
  );

  // 拖拽后 重新设置列表宽度
  const handleResize = useCallback(
    (index) => {
      return (txt: any, Resize: any) => {
        const temp = [...rescolumns];
        temp[index] = { ...temp[index], width: Resize.size.width };
        setResColumns(temp);
      };
    },
    [rescolumns],
  );

  // 把 columns 设置可拖拽的cell
  const columnsMap: any[] = useMemo(() => {
    return (
      rescolumns?.map((column: any, index) => {
        return {
          ...column,
          onHeaderCell: (col: any) => ({
            width: col.width,
            onResize: handleResize(index),
            isNotResizable: col.isNotResizable
          }),
        };
      }) || []
    );
  }, [rescolumns, handleResize]);

  useEffect(() => {
    const showTotal = {
      showTotal: (total: number, range: number[]) => {
        if (showTotalNum) {
          return `共{${props.pagination ? props.pagination?.total : 0}}条结果`;
        } else {
          return '';
        }
      },
    };
    if (!hidePagination) {
      setTablePagination(Object.assign({}, pagination ?? {}, showTotal));
    } else {

      className={classes.base_table_com}

  );
};

interface CommonColumn<T> extends ColumnType<T> {
  hide?: boolean;
}

export interface ICommonTableProps<RecordType> extends TableProps<RecordType> {
  showTotalNum?: boolean;
  hidePagination?: boolean;
  columns: CommonColumn<RecordType>[]; // 重写 columns 类型
  paddingVertical?: number; // 上下padding
  paddingHorizontal?: number;// 左右padding
}

使用DragTable 组件

import { createUseStyles } from 'react-jss';
import { useEffect, useMemo, useState, useRef } from 'react';
import { DragTable } from './drapTable';
import { Space } from "antd"

const TablePage = () => {
  const columns = [
    {
      title: '操作',
      width: 60,
      isNotResizable: true, // 设置操作栏固定不可拖拽
      render: (_, record) => (
        <Space size="middle">
          <a>删除</a>
        </Space>
      ),
    },
    {
      title: '编码',
      dataIndex: 'code',
      width: 100,
    },
    {
      title: '名称',
      width: 100,
      dataIndex: 'name',
    },
    {
      title: '测试',
      dataIndex: 'test',
      width: 400,
    },
    {
      title: '描述',
      dataIndex: 'des',
      width: 400,
    },
  ];
  const dataSource = [
    { id: 1, code: '001', name: '我是name1', test: '测试一下1', des: '描述一下' },
    { id: 2, code: '002', name: '我是name2', test: '测试一下2', des: '描述一下2' },
    { id: 3, code: '003', name: '我是name3', test: '测试一下3', des: '描述一下3' },
    { id: 4, code: '004', name: '我是name4', test: '测试一下4', des: '描述一下4' },
    { id: 5, code: '005', name: '我是name5', test: '测试一下5', des: '描述一下5' },
    { id: 6, code: '006', name: '我是name6', test: '测试一下6', des: '描述一下6' },
    { id: 7, code: '007', name: '我是name7', test: '测试一下7', des: '描述一下7' },
    { id: 8, code: '008', name: '我是name8', test: '测试一下8', des: '描述一下8' },
    { id: 9, code: '009', name: '我是name9', test: '测试一下9', des: '描述一下9' },
  ];
  return (
    <>
      <DragTable
        rowKey="id"
        paddingVertical={8}
        paddingHorizontal={10}
        columns={columns}
        dataSource={dataSource}
        scroll={{ x: 'max-content', y : 250 }}
      />
    </>
  );
};
export default TablePage;

滚动条样式

/* 设置滚动条的宽度和背景色 */
::-webkit-scrollbar {
  width: 6px; /* 垂直滚动条的宽度 */
  height: 6px; /* 水平滚动条的宽度 */
  background-color: #f5f5f5; /* 滚动条的背景色 */
}

/* 设置滚动条的滑块 */
::-webkit-scrollbar-thumb {
  background-color: #999; /* 滑块的背景色 */
  border-radius: 4px; /* 滑块的圆角 */
  cursor: pointer;
}

/* 设置滚动条的轨道 */
::-webkit-scrollbar-track {
  background-color: #f5f5f5; /* 轨道的背景色 */
}
