react-table没有正确地对十进制数进行排序

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

const CustomNumberSort = (a, b, columnId) => {
  const numA = parseFloat(a.values[columnId]);
  const numB = parseFloat(b.values[columnId]);

  if (numA < numB) {
    return -1;
  }
  if (numA > numB) {
    return 1;
  }
  return 0;
};

const Table = () => {
  const data = [
    { id: 1, name: 'John Doe', age: '25.5' },
    { id: 2, name: 'Jane Smith', age: '30.25' },
    { id: 3, name: 'Bob Johnson', age: '27.75' },
  ];

  const columns = [
    { Header: 'ID', accessor: 'id' },
    { Header: 'Name', accessor: 'name' },
    { Header: 'Age', accessor: 'age', sortType: CustomNumberSort },
  ];

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

  return (
    <table {...getTableProps()}>
      <thead>
        {headerGroups.map((headerGroup) => (
          <tr {...headerGroup.getHeaderGroupProps()}>
            {headerGroup.headers.map((column) => (
              <th {...column.getHeaderProps(column.getSortByToggleProps())}>
                {column.render('Header')}
                {column.isSorted ? (column.isSortedDesc ? ' 🔽' : ' 🔼') : ''}
              </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 Table;
