复杂 HTML table 未验证:table 行 "exceeded the column count established by the first row"

Complex HTML table not validating: table row "exceeded the column count established by the first row"

validator.w3.org 给我错误:

A table row was 4 columns wide and exceeded the column count established by the first row (1).

看起来像这样:

|1|2.1|2.2    |
| |3.1|3.2|3.3|
| |4.1|4.4|4.5|
<table>
  <tbody>
    <tr>
      <td rowspan="4"> 1 </td>
    </tr>
    <tr>
      <td> 2.1 </td>
      <td colspan="2"> 2.2 </td>
    </tr>
    <tr>
      <td> 3.1 </td>
      <td> 3.2 </td>
      <td> 3.3 </td>
    </tr>
    <tr>
      <td> 4.1 </td>
      <td> 4.2 </td>
      <td> 4.3 </td>
    </tr>
  </tbody>
</table>

我简化了数据,代码来自艾萨克·牛顿爵士的自然哲学的数学原理,显然他不明白HTMLtable规则比我做的更好。

您必须合并前两行并更改第一个字段的行跨度:

<table>
  <tbody>
    <tr>
      <td rowspan="3"> 1 </td>
      <td> 2.1 </td>
      <td colspan="2"> 2.2 </td>
    </tr>
    <tr>
      <td> 3.1 </td>
      <td> 3.2 </td>
      <td> 3.3 </td>
    </tr>
    <tr>
      <td> 4.1 </td>
      <td> 4.2 </td>
      <td> 4.3 </td>
    </tr>
  </tbody>
</table>
