<table id="myTable">
  <thead>
    <tr>
      <th>Name</th>
      <th>Age</th>
      <!-- 新添加的列 -->
      <th>City</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td>John Doe</td>
      <td>25</td>
      <td>New York</td>
    </tr>
    <tr>
      <td>Jane Smith</td>
      <td>30</td>
      <td>London</td>
    </tr>
    <!-- 其他行数据 -->
  </tbody>
</table>

$(document).ready(function() {
  var table = $('#myTable').DataTable();
  
  // 启用列搜索
  table.columns().every(function() {
    var column = this;
    $('input', this.header()).on('keyup change', function() {
      if (column.search() !== this.value) {
        column.search(this.value).draw();
      }
    });
  });
});
