Antd V3。表组件。如何计算列值之和

import React from 'react';
import { Table } from 'antd';

const dataSource = [
  {
    id: 1,
    name: 'John',
    age: 25,
    score: 80,
  },
  {
    id: 2,
    name: 'Jane',
    age: 30,
    score: 90,
  },
  // 更多数据...
];

const columns = [
  {
    title: 'ID',
    dataIndex: 'id',
    key: 'id',
  },
  {
    title: 'Name',
    dataIndex: 'name',
    key: 'name',
  },
  {
    title: 'Age',
    dataIndex: 'age',
    key: 'age',
  },
  {
    title: 'Score',
    dataIndex: 'score',
    key: 'score',
  },
  {
    title: 'Total Score',
    key: 'totalScore',
    render: (text, record) => {
      let total = 0;
      dataSource.forEach((item) => {
        total += item.score;
      });
      return total;
    },
  },
];

const TableComponent = () => {
  return <Table dataSource={dataSource} columns={columns} />;
};

export default TableComponent;
