longtabu 和 rotatebox 导致表格太宽

Question

我正在尝试制作一个固定的全宽表格，该表格可能跨越多个页面。我发现旋转标题会\rotatebox弄乱尺寸计算，但我找不到解决方法。\makebox例如被忽略。

测试用例：

\documentclass{article}
\usepackage{graphics}
\usepackage{longtable}
\usepackage{tabu}
\usepackage{fancyhdr}    

\pagestyle{fancy}
\begin{document}
\begin{longtabu} to \linewidth{Xll}
some simple text & \rotatebox{90}{some really really really long text} & \rotatebox{90}{some really really really long text} \\
some simple text & \multicolumn{2}{l}{some much shorter text} \\
\end{longtabu}
\end{document}

Answer 1

并\multicolumn没有被忽略，它只是不参与宽度计算。（通常有足够多的非跨越单元格，所以这不是问题，但在这里却存在问题）。

如果你把规则放入其中，会更容易看到：

\documentclass{article}
\usepackage{graphics}
\usepackage{longtable}
\usepackage{tabu}
\usepackage{fancyhdr}    

\pagestyle{fancy}
\begin{document}
\begin{longtabu} to \linewidth{|X|l|l|}
some simple text & \rotatebox{90}{some really really really long text} & 
\rotatebox{90}{some really really really long text} \\
some simple text & \multicolumn{2}{l}{some much shorter text} \\
\end{longtabu}
\end{document}

因此，X除了旋转标题所需的空间之外，获取所有空间，然后放入多列，表格太宽

Overfull \hbox (72.6446pt too wide) in alignment at lines 12--12

如果第二列和第三列中有一些非跨越单元格，它们会更早被看到，并且该X列会分配较少的空间。

如果确实没有这样的条目，您可以在\kill未排版的行中添加一些：

\documentclass{article}
\usepackage{graphics}
\usepackage{longtable}
\usepackage{tabu}
\usepackage{fancyhdr}    

\pagestyle{fancy}
\begin{document}
\begin{longtabu} to \linewidth{|X|l|l|}
aaa&x\hspace{2.1cm}x&x\hspace{2.1cm}x\kill
some simple text & \rotatebox{90}{some really really really long text} &  
\rotatebox{90}{some really really really long text} \\
some simple text & \multicolumn{2}{l}{some much shorter text} \\
\end{longtabu}
\end{document}
