如何使用DataTables使两行显示为一行？

<table id="myTable">
  <thead>
    <tr>
      <th>列1</th>
      <th>列2</th>
      <th>列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>
  </tbody>
</table>

$(document).ready(function() {
  $('#myTable').DataTable({
    "responsive": true,
    "columnDefs": [
      { "visible": false, "targets": [1, 2] },
      { "targets": 0, "render": function(data, type, row) {
          return data + ' ' + row[1] + ' ' + row[2];
        }
      }
    ]
  });
});
