如何在flex布局中处理表格的滚动？

<style>
  .container {
    display: flex;
    width: 500px;
    height: 300px;
    overflow: auto;
  }

  table {
    width: 100%;
    border-collapse: collapse;
  }

  th,
  td {
    padding: 8px;
    border: 1px solid black;
  }

  th {
    position: sticky;
    top: 0;
    background-color: white;
  }
</style>

<div class="container">
  <table>
    <thead>
      <tr>
        <th>Header 1</th>
        <th>Header 2</th>
        <th>Header 3</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>Data 1</td>
        <td>Data 2</td>
        <td>Data 3</td>
      </tr>
      <!-- more rows -->
    </tbody>
  </table>
</div>
