React-tables如何获取表列名称？

import React from 'react';
import ReactTable from 'react-table';

const data = [
  { name: 'John', age: 25, city: 'New York' },
  { name: 'Jane', age: 30, city: 'London' },
  { name: 'Bob', age: 35, city: 'Paris' },
];

const columns = [
  { Header: 'Name', accessor: 'name' },
  { Header: 'Age', accessor: 'age' },
  { Header: 'City', accessor: 'city' },
];

const MyTable = () => {
  return (
    <ReactTable
      data={data}
      columns={columns}
    />
  );
};

export default MyTable;
