You have two options: (1) adding a specialized class in the HTML to the last row; or (2) using the :last-child
pseudo class in your CSS.
您有两个选择:(1)在 HTML 中的最后一行添加一个专门的类;或 (2):last-child
在 CSS 中使用伪类。
Option 1: Specialized Class
选项 1:专业课
If you can apply classes to your HTML, you can add a specialized class to the final row. If your markup is being generated by a server-side script (eg. a PHP script), you will need to edit that script to add similar markup.
如果您可以将类应用于 HTML,则可以在最后一行添加一个专门的类。如果您的标记是由服务器端脚本(例如 PHP 脚本)生成的,您将需要编辑该脚本以添加类似的标记。
HTML:
HTML:
<table>
<tr>
<td>
</td>
</tr>
<tr>
<td>
</td>
</tr>
<tr class="last">
<td>
</td>
</tr>
</table>
CSS:
CSS:
table
{
border-collapse:collapse;
}
tr
{
border-bottom: 1px solid #000;
}
tr.last
{
border-bottom: none;
}
Option 2: CSS Pseudo Class
选项 2:CSS 伪类
The alternative is to use the :last-child
CSS pseudo class. Using the :last-child
class doesn't require any changes to the HTML and so may be a better choice if you aren't able to change the HTML. The CSS is almost identical to the above:
另一种方法是使用:last-child
CSS 伪类。使用:last-child
该类不需要对 HTML 进行任何更改,因此如果您无法更改 HTML,则可能是更好的选择。CSS 几乎与上述相同:
CSS:
CSS:
table
{
border-collapse:collapse;
}
tr
{
border-bottom: 1px solid #000;
}
tr:last-child
{
border-bottom: none;
}
The drawback of this approach is that versions of Internet Explorer before 9 don't supportthe :last-child
pseudo class.
这种方法的缺点是9之前的Internet Explorer版本不支持的:last-child
伪类。

I know this is an old question, but it's worth mentioning that now with CSS3 all you have to do is us the not()
selector in your CSS, like this:
我知道这是一个老问题,但值得一提的是,现在有了 CSS3,你所要做的就是我们not()
CSS 中的选择器,就像这样:
tr:not(:last-child) {
border-bottom: 1px solid #E3E3E3;
}
回答by Bryan Butler
tr:last-child td {
border-bottom: none;
}
Saves you putting a class on the last tag.
保存您在最后一个标签上放置一个类。
回答by Web Designer cum Promoter
this is used with any class call in html
这与 html 中的任何类调用一起使用
tr:last-child {
border-bottom: none;
}

If you're using jQuery you can use the following script
如果您使用 jQuery,则可以使用以下脚本
$(document).ready(function() {
$(".tableClass tr:not(:last) > td").css('border-bottom', ' 1px solid #DDD');
});

You can also use this way
你也可以用这种方式
table tr:not(:last-of-type) { border-bottom: none; }
