我在 longtabu 环境中遇到了包括标题在内的麻烦。代码如下所示，它引发了大量错误。
\documentclass{article}
\usepackage{longtable}
\usepackage{tabu}
\begin{document}
\newpage
\begin{longtabu} to 1\textwidth {l X[c] X[c] X[c] X[c] X[c] X[c] X[c]}
\caption{Hello}

答案1
可以\caption{}在内使用tabu，只需\\在行末尾添加，例如：
\documentclass{article}
\usepackage{longtable}
\usepackage{tabu}
\begin{document}
\begin{longtabu}{l}
\caption{This is a caption} \\
This is some table data \\
\end{longtabu}
\end{document}
任何荣誉都归功于@cfr，他已经在评论部分，但不幸的是没有提供答案（根据 SE 问答范式），因此懒人（比如我）可能会错过解决方案。
