我有一张桌子:
<table>
<thead>
<tr>
<td>col 1</td>
<td>col 2</td>
<td>col 3</td>
</tr>
</thead>
<tbody>
<tr>
<td>row 1</td>
<td class="editable">value 1</td>
<td class="editable">value 2</td>
</tr>
<tr>
<td>row 2</td>
<td class="editable">value 1</td>
<td class="editable">value 2</td>
</tr>
<tr>
<td>row 3</td>
<td class="editable">value 1</td>
<td class="editable">value 2</td>
</tr>
<tr>
<td>row 4</td>
<td class="editable">value 1</td>
<td class="editable">value 2</td>
</tr>
<tr>
<td>row 5</td>
<td class="editable">value 1</td>
<td class="editable">value 2</td>
</tr>
</tbody>
</table>
如何从 中仅选择(仅使用 CSS 选择器)一个元素td.editable
?jQuery:first
选择器的模拟是可以接受的。
