虽然这个问题已经出现在这个论坛中,但它并没有解决我的特殊问题,因为我的列是在表行元素中专门定义的。我尝试过使用colgroup和colspan,每次添加都会导致更多的错误和警告。我不明白的是,我的计数并不符合(4)我能看到的。我猜测括号内的4表示4列。在我的研究中,我访问了w3.org桌面结构,WDG,并观看了许多Youtube视频以及咨询Web Development&设计基础文本第7版。如果我理解警告意味着,我可以解决这个问题。所以我来这里寻求帮助。这是我的代码。我很感激任何建议或线索。

答案 0 :(得分:0)
您已将此表格<td>
嵌套到一个<td>
中。但围绕<td>
的是其中唯一<td>
行(即最后一行),与所有其他行中的{{1}}数量冲突都有四个。)
