如何仅取消选择网格中的某些行？

<table id="grid">
  <tr>
    <td><input type="checkbox" class="row-checkbox"></td>
    <td>行1</td>
  </tr>
  <tr>
    <td><input type="checkbox" class="row-checkbox"></td>
    <td>行2</td>
  </tr>
  <tr>
    <td><input type="checkbox" class="row-checkbox"></td>
    <td>行3</td>
  </tr>
</table>

<script>
  const checkboxes = document.querySelectorAll('.row-checkbox');

  checkboxes.forEach((checkbox) => {
    checkbox.addEventListener('change', (event) => {
      const rowIndex = Array.from(checkboxes).indexOf(event.target);
      const row = event.target.parentNode.parentNode;

      if (event.target.checked) {
        row.classList.add('selected');
      } else {
        row.classList.remove('selected');
      }
    });
  });
</script>
