如果传入的json没有内置的单元格函数，我该如何实现React-tables列数组的单元函数

import React from 'react';
import { useTable } from 'react-table';

const MyTable = () => {
  const data = [
    { name: 'John', age: 25 },
    { name: 'Jane', age: 30 },
    { name: 'Bob', age: 35 },
  ];

  const columns = [
    { Header: 'Name', accessor: 'name' },
    { Header: 'Age', accessor: 'age', Cell: ({ value }) => <span>{value}</span> },
    // 添加自定义的单元格函数
    { Header: 'Custom', accessor: 'age', Cell: ({ value }) => <span>{value * 2}</span> },
  ];

  const {
    getTableProps,
    getTableBodyProps,
    headerGroups,
    rows,
    prepareRow,
  } = useTable({ columns, data });

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map(headerGroup => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map(column => (
              <th {...column.getHeaderProps()}>{column.render('Header')}</th>
            ))}
          </tr>
        ))}
      </thead>
      <tbody {...getTableBodyProps()}>
        {rows.map(row => {
          prepareRow(row);
          return (
            <tr {...row.getRowProps()}>
              {row.cells.map(cell => (
                <td {...cell.getCellProps()}>{cell.render('Cell')}</td>
              ))}
            </tr>
          );
        })}
      </tbody>
    </table>
  );
};

export default MyTable;
