Answer 2

试试这个：

tr:nth-child(2) > td:nth-child(n+2):nth-child(-n+5) { 
 
    color: red; 
 
}

<table> 
 
    <tr> 
 
    <td>one</td> 
 
    <td>two</td> 
 
    <td>three</td> 
 
    <td>four</td> 
 
    <td>five</td> 
 
    <td>six</td> 
 
    </tr> 
 
    <tr> 
 
    <td>one</td> 
 
    <td>two</td> 
 
    <td>three</td> 
 
    <td>four</td> 
 
    <td>five</td> 
 
    <td>six</td> 
 
    </tr> 
 
    <tr> 
 
    <td>one</td> 
 
    <td>two</td> 
 
    <td>three</td> 
 
    <td>four</td> 
 
    <td>five</td> 
 
    <td>six</td> 
 
    </tr> 
 
</table>
