如何使用React将一组数据正确地映射到表中

npx create-react-app my-app
cd my-app
npm start

import React from 'react';

const Table = ({ data }) => {
  return (
    <table>
      <thead>
        <tr>
          <th>ID</th>
          <th>Name</th>
          <th>Age</th>
        </tr>
      </thead>
      <tbody>
        {data.map((item) => (
          <tr key={item.id}>
            <td>{item.id}</td>
            <td>{item.name}</td>
            <td>{item.age}</td>
          </tr>
        ))}
      </tbody>
    </table>
  );
};

export default Table;

import React from 'react';
import Table from './Table';

const App = () => {
  const data = [
    { id: 1, name: 'John', age: 25 },
    { id: 2, name: 'Jane', age: 30 },
    { id: 3, name: 'Bob', age: 35 },
  ];

  return (
    <div>
      <h1>Table Example</h1>
      <Table data={data} />
    </div>
  );
};

export default App;

import React from 'react';
import ReactDOM from 'react-dom';
import App from './App';

ReactDOM.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
  document.getElementById('root')
);

npm start
