基于ant.design4.3.1实现table的编辑

• 实现效果如图所示
• 

import React, { useState } from "react";
import { Table, Input, InputNumber } from 'antd'
import { MinusCircleOutlined, PlusCircleOutlined } from "@ant-design/icons";
import styles from './style.less'

  b2bPrice: string,
  minNumber: string,
  maxNumber: string,
  unit: string,

  callback?: (data: any) => void;
}

  handleAdd: (value: number) => void;
  handleRemove: (value: number) => void;
  handleChange: (value: string, _: string, index: number) => void;
  len: number;
}

const columns = (actions: ActionType) => {
  const {handleAdd, handleRemove, handleChange, len} = actions
  return [
    {
      title: '采购量最小值',

export default ListTableEdit;

• 我这儿的例子都是数字输入框，如果是input输入框value = e.target.value
• 其他文件
  css

.listTableEdit {
  :global {
    .ant-table-tbody > tr > td .ant-input-number {
      width: 100%;
    }

    .ant-table-thead > tr > th, .ant-table-tbody > tr > td, .ant-table tfoot > tr > th, .ant-table tfoot > tr > td {
      padding: 4px;
      text-align: center;
    }

    .ant-table-thead > tr > th {
      color: rgba(0, 0, 0, 0.65);
      font-weight: normal;
    }
  }
  .iconButton {
    margin: 0 8px;
    color: @primary-color;
    font-size: 16px;
    line-height: 32px;
  }
}
