如何实现一个粘性的表头和几列(在每列上有复选框或输入)

<div class="table-container">
  <table>
    <thead>
      <tr>
        <th>表头1</th>
        <th>表头2</th>
        <th>表头3</th>
      </tr>
    </thead>
    <tbody>
      <tr>
        <td>数据1</td>
        <td>数据2</td>
        <td>数据3</td>
      </tr>
      <tr>
        <td>数据4</td>
        <td>数据5</td>
        <td>数据6</td>
      </tr>
      <!-- 更多数据行... -->
    </tbody>
  </table>
</div>

.table-container {
  overflow: auto;
  height: 300px; /* 设置容器的高度，使表格可以滚动 */
}

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

th, td {
  padding: 10px;
  border: 1px solid #ccc;
}

thead th {
  position: sticky;
  top: 0;
  background-color: #f5f5f5;
  z-index: 1;
}

tbody td:first-child {
  position: sticky;
  left: 0;
  background-color: #f5f5f5;
  z-index: 1;
}

// 在每列上添加复选框或输入框
const table = document.querySelector('table');
const rows = table.rows;

for (let i = 0; i < rows.length; i++) {
  const row = rows[i];
  const cells = row.cells;

  for (let j = 0; j < cells.length; j++) {
    const cell = cells[j];
    const checkbox = document.createElement('input');
    checkbox.type = 'checkbox';
    cell.appendChild(checkbox);
  }
}
