如何增加 booktabs 表中 \crule 后的空间？

Question

在下面的 MWE 中创建的表格中，我希望 crule 和第三行之间的间距稍微大一些，而第二行文本和 crule 之间的间距稍微小一些。我该怎么做？

\documentclass{article} 
\usepackage{booktabs}
\usepackage{multirow}

\begin{document}

\renewcommand{\arraystretch}{1.2}

\begin{table}[tp]
\caption{Minimum Working Example}
\centering
\begin{tabular}{cccc}
\toprule
 & & \multicolumn{2}{c}{First Dimension} \\
 & & 1st D Value 1  & 1st D Value 2      \\ \cline{3-4} 
 \multirow{2}*{Second dimension} & 2nd D Value1 & Outcome(1,1)  & Outcome(1,2) \\
 & 2nd D Value2 & Outcome(2,1) & Outcome(2,2)       \\
\bottomrule
\end{tabular}
\end{table}
\end{document}

Answer 1

中没有\crule宏booktabs，但是\cmidrule，与 含义相同\cline，但提供更多空间。

如果常规间距（由\aboverulesep和控制\bottomrulesep）不够，则\addlinespace可以注入显式间距：

\documentclass{article} 
\usepackage{booktabs}
\usepackage{multirow}


\newlength{\ridiculouslylargecmidrulesep}
\setlength{\ridiculouslylargecmidrulesep}{50pt}

\begin{document}

\renewcommand{\arraystretch}{1.2}

\begin{table}[tp]
\caption{Minimum Working Example}
\centering
\begin{tabular}{cccc}
\toprule
 & & \multicolumn{2}{c}{First Dimension} \\
 & & 1st D Value 1  & 1st D Value 2      \\ \cmidrule{3-4} 
 \multirow{2}*{Second dimension} & 2nd D Value1 & Outcome(1,1)  & Outcome(1,2) \\
 & 2nd D Value2 & Outcome(2,1) & Outcome(2,2)       \\
\bottomrule
\end{tabular}
\end{table}


\begin{table}[tp]
\caption{Minimum Working Example}
\centering
\begin{tabular}{cccc}
\toprule
 & & \multicolumn{2}{c}{First Dimension} \\
 & & 1st D Value 1  & 1st D Value 2      \\ \addlinespace[\ridiculouslylargecmidrulesep]
\cmidrule{3-4}  \addlinespace[\ridiculouslylargecmidrulesep]
 \multirow{2}*{Second dimension} & 2nd D Value1 & Outcome(1,1)  & Outcome(1,2) \\ 
 & 2nd D Value2 & Outcome(2,1) & Outcome(2,2)       \\
\bottomrule
\end{tabular}
\end{table}

\end{document}

Answer 2

我认为，您的表格可能是罕见的情况，如果使用\hline和\cline以及适当放置的垂直线，比使用包的线条绘制宏看起来更好booktabs。

\documentclass{article}
\usepackage{multirow}
\usepackage[skip=0.333\baselineskip]{caption}

\begin{document}

\begin{table}[ht!]
\renewcommand{\arraystretch}{1.6}

\caption{Minimum Working Example}
\centering
\begin{tabular}{|*{4}{c|}}
\cline{3-4}
\multicolumn{2}{c|}{} & \multicolumn{2}{c|}{First Dimension} \\
\cline{3-4}
\multicolumn{2}{c|}{} & 1st D Value 1  & 1st D Value 2  \\ 
\hline
\multirow{2}{*}{Second dimension} & 2nd D Value1 & Outcome(1,1)  & Outcome(1,2) \\
\cline{2-4}
 & 2nd D Value2 & Outcome(2,1) & Outcome(2,2)       \\
\hline
\end{tabular}
\end{table}

\end{document}
