As an option:

  border-collapse: collapse;
  border-spacing: 0;
}

table td {
  padding: 4px 16px;
  text-align: center;
  border: solid 1px #ccc;
}

table td:empty {
  height: 0;
  border: 0;
  padding: 0;
}

<table>
  <tr>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
    <td></td>
  </tr>
  <tr>
    <td colspan="3">1</td>
    <td colspan="3">2</td>
  </tr>
  <tr>
    <td colspan="2">3</td>
    <td colspan="2">4</td>
