You can iterate over when the data came into HTML elements:

<table>
  <thead>
    <th>Color</th>
    <th>Name</th>
    <th>Age</th>
  </thead>
  <tbody>
    {user.map(userData => (
      // A unique key for each element
      <tr key={userData.name}>
        <td>{userData.name}</td>
        <td>{userData.color}</td>
        <td>{userData.age}</td>
      </tr>
    ))}
  </tbody>
</table>;
