我想自动调整 tabularx 行的高度，使其占用最小的空间。
考虑以下代码：
\small
\begin{center}
\begin{tabularx}{\textwidth}{|X|X|X|}
\hline
\textbf{AA} & \textbf{[BB]-[CC]} & \textbf{DD \& general EE}\\
\hline
aa aa aa aa aa aa aa aa aa aa & aa aa aa aa aa aa aa aa aa aa & aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa \\
\hline

\hline
\end{tabularx}
\end{center}
\normalsize
如果你显示它，你会发现类似这样的内容：
我希望第三列更宽，这样整行占用的高度更小。但我希望 latex 能自动帮我完成这个任务（我不想考虑第三列应该有多宽，这样整行占用的高度更小）。我该怎么做？
在这个例子中，每一行包含相同的元素，但通常行可能具有不同的内容。
答案1
通过使用tabulary包：
\documentclass{article}
\usepackage{tabulary}
\begin{document}
\begin{center}
\small
\begin{tabulary}{\textwidth}{|L|L|L|}
\hline
\textbf{AA} & \textbf{[BB]-[CC]} & \textbf{DD \& general EE}\\
\hline
aa aa aa aa aa aa aa aa aa aa & aa aa aa aa aa aa aa aa aa aa & aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa \\

aa aa aa aa aa aa aa aa aa aa & aa aa aa aa aa aa aa aa aa aa & aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa aa \\
\hline
\end{tabulary}
\end{center}
\end{document}
如果您喜欢将列标题放在一行中，xopu 应该定义列的最小宽度。为此，在您的案例中，请\tymin=5em在前面添加\begin{tabulary}：
\documentclass{article}
\usepackage{tabulary}
\begin{document}
\begin{center}
\small
\tymin=5em
\begin{tabulary}{\textwidth}{|L|L|L|}
% table body is the same as before
\end{tabulary}
\end{center}
\end{document}
答案2
直观地讲，您可以通过设置列宽以使单元格的深度（大致）相等来实现您的目标。如果您希望继续使用环境tabularx，我建议您将第三列的可用宽度设置为前两列可用宽度的十倍 [10！]。
\documentclass{article} % or some other suitable document class
\usepackage{tabularx,ragged2e}
\newcolumntype{L}[1]{>{\hsize=#1\hsize\RaggedRight\hspace{0pt}}X}
\begin{document}
\begin{center}
\small
\setlength\tabcolsep{3pt} % default: 6pt
\begin{tabularx}{\textwidth}{|L{0.25}|L{0.25}|L{2.50}|} % 0.25+0.25+2.5=3
\hline
\textbf{AA} & \textbf{[BB]-[CC]} & \textbf{DD \& general EE}\\

答案3
您可以使用\hsize=<factor>\hsize更具可定制性的技巧。
\documentclass{article}
\usepackage{tabularx}
\newcolumntype{Y}[1]{>{\hsize=\fpeval{#1}\hsize}X}
\begin{document}
\begin{center}
\small
\begin{tabularx}{\textwidth}{|Y{1/2}|Y{1/2}|Y{2}|}

\end{tabularx}
\end{center}
\end{document}
参数的总和Y应等于所需列的数量X，在本例中为 3。
这些参数可以是分数，这简化了计算，但Y{0.5}对于这种情况您也可以输入。
和
|Y{1/2}|Y{1}|Y{3/2}|
你得到
注意\small里面的内容center。很少（如果有的话）需要\normalsize在 LaTeX 文档中发布。
