在html中创建其他表

Question

我想创建一个表，该表的行数很少，但列较大，第4列的右边界的厚度是其他边界的2倍。

示例：

|  |  |  |  ||  |  |  |  ||  |  |  |  ||  |  |  |  ||
|  |  |  |  ||  |  |  |  ||  |  |  |  ||  |  |  |  ||
|  |  |  |  ||  |  |  |  ||  |  |  |  ||  |  |  |  ||

将||视为|的两倍宽度。

Answer 1

使用nth-child CSS选择器

td{ border-right:1px solid #ccc}

td:nth-child(4n){
  border-right-width:10px;
}

<table cellpadding=0 cellspacing=0>
<tr>
  <td>Col 1</td>
  <td>Col 2</td>
  <td>Col 3</td>
  <td>Col 4</td>
  <td>Col 5</td>
  <td>Col 6</td>
  <td>Col 7</td>
  <td>Col 8</td>
  <td>Col 9</td>

</tr>
<tr>
  <td>Col 1</td>
  <td>Col 2</td>
  <td>Col 3</td>
  <td>Col 4</td>
  <td>Col 5</td>
  <td>Col 6</td>
  <td>Col 7</td>
  <td>Col 8</td>
  <td>Col 9</td>

</tr>
<tr>
  <td>Col 1</td>
  <td>Col 2</td>
  <td>Col 3</td>
  <td>Col 4</td>
  <td>Col 5</td>
  <td>Col 6</td>
  <td>Col 7</td>
  <td>Col 8</td>
  <td>Col 9</td>

</tr>
</table>
