我有一个动态生成的日历，由表格组成，主表中的每个月都是一个单元格，在这个单元格中，还有另一个表格，其中包含每月每天的单元格。
我需要抓住整个桌子中的最后一天细胞并移除其左边界，而不是每个月的最后一天细胞，而是上个月的最后一天细胞。
是否可以单独执行此css？我尝试过使用last-child bit每个月的最后一天，这不是我需要的。
我在这里创建了一个演示，以明确我的意思：http://jsfiddle.net/9bXEp/
如果向右滚动，您将看到2014年8月和下面两行，最后一个单元格包含21和T.如果仔细观察并检查这些单元格，您会看到它左边有一个边框，导致与桌边的双边框。这就是我需要删除的东西，我不能直接应用一个类，因为在我的应用程序中，表是由php生成的。
这是代码，但jsfiddle将更清晰

答案 0 :(得分：0)
使用
.inner_container:last-child tr:last-child .no-b2:last-child {
border-left: none;
}
选择最后一个.inner_container，然后选择最后一个tr（即数字行），然后选择最后一个.no-b2（即一天）。
哦，你确定它不是border-right吗？
