React-Table中的自动列不使用JSON数组

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

const MyTable = () => {
  const [data, setData] = useState([]);

  useEffect(() => {
    // 获取数据并解析
    fetch('your-api-endpoint')
      .then(response => response.json())
      .then(jsonData => {
        setData(jsonData);
      });
  }, []);

  const columns = data.length > 0 ? Object.keys(data[0]).map(key => ({
    Header: key,
    accessor: key
  })) : [];

  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;
