CSS并选择最后一个td

Question

总结：detailsview的每个字段行都有2个td，他们的第一个td可以应用左边框。但第二个（因此字段tr（行）中最右边的单元格）无法应用。即使我试过

.dvRowEven td:nth-last-child(even)

或

.dvRowOdd td:last-of-type

现在我的完整信息：

我正在尝试为DetailsView（asp.net控件）编写css。

我完成了页眉和页脚。第一个td单元格（使用它们进行标记）具有1px实线边框（带有背景图像）但是下一个td单元格（用于放置控件，如文本框，下拉列表等）无法应用相同的图像：

.dvRowEven td:nth-last-child(even)
{
    border-right: solid 1px #B4B4B2;
    padding-left: 5px;
    padding-bottom: 3px;

    background-position:right top;
    background-image: url('../images/dv/tdLeftBorder.gif');
    background-repeat: repeat-y;
}
.dvRowOdd td:last-of-type
{
    border-right: solid 1px #B4B4B2;
    padding-left: 5px;
    padding-bottom: 3px;

    background-position:right top;
    background-image: url('../images/dv/tdLeftBorder.gif');
    background-repeat: repeat-y;
    background-color:Yellow;
}

css风格。我添加了整体风格。

支持第一个/最后一个元素CSS规则是不稳定的，并且在所有浏览器中都没有标准化。我发现的最好的折衷方案是在CSS中添加一个额外的“.last”类，并使用服务器端代码将该类放在最后一个TD中。
