{longtabu} 无法编译

Question

我从同事的文档中复制粘贴了一个长表（经许可），以帮助我创建长表。尝试编译时，编译在 处停止，\end{longtabu}如果我同时停用两者\begin{longtabu}，则\end{longtabu}似乎\end{landscape}是问题所在。停用{landscape}会产生新问题。我做错了什么？

Answer 1

复制完所有需要的定义后，它基本上就可以正常工作了，但使用一次\midrule 会产生错误，不知道为什么看起来像是某种禁忌怪异。我在这里注释掉了它，但您可以使用\hline或其他东西，或者在完整文档的上下文中它可以工作。
