\setlength{\extrarowheight}{1pt} 具有负的额外高度吗？

Question

有没有办法让数组包垂直挤压，而不是扩展行？

以下是 MWE：

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{booktabs}
\begin{document}
\begin{tabular}{lll}
\toprule
     Time & Money & Length \\
\midrule
\rowcolor{yellow} Contemporary \\
    Sec  &  \$ & inch\\  
    Hour  & cents  & cm \\  
    \midrule
\rowcolor{yellow} Ancient \\
    ?  &  Dinar & Yard \\  
    horae  &   Drachma & Palm \\  
    \bottomrule
\end{tabular}
\end{document}

我的输出是：

我试图让黄色矩形接触\midrule其上方， 没有使线路高度高于必要水平。

** 编辑 **

请注意，当我使用时问题就消失了\hline，但是，我真的很喜欢的专业外观\midrule，我宁愿不自己模仿它。

Answer 1

您可以在第一步中删除由包确定的规则周围的垂直空格booktabs，然后在第二步使用包向单元格添加垂直空格cellspace：

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{booktabs, cellspace}
\setlength\abovetopsep{0pt}
\setlength\belowrulesep{0pt}
\setlength\cellspacetoplimit{4pt}
\setlength\cellspacebottomlimit{4pt}

\begin{document}
\begin{tabular}{Slll}
\toprule
     Time & Money & Length \\
\midrule
\rowcolor{yellow} Contemporary \\
    Sec  &  \$ & inch\\
    Hour  & cents  & cm \\
    \midrule
\rowcolor{yellow} Ancient \\
    ?  &  Dinar & Yard \\
    horae  &   Drachma & Palm \\
    \bottomrule
\end{tabular}
\end{document}

Answer 2

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{booktabs}
\setlength{\belowrulesep}{0pt}% distance below booktabs rules (not \bottomrule)
\setlength{\aboverulesep}{0pt}% distance above booktabs rules (not \toprule)
\begin{document}
\begin{tabular}{lll}
\toprule
     Time & Money & Length \\
\midrule
\rowcolor{yellow} Contemporary \\
    Sec  &  \$ & inch\\  
    Hour  & cents  & cm \\  
    \midrule
\rowcolor{yellow} Ancient \\
    ?  &  Dinar & Yard \\  
    horae  &   Drachma & Palm \\  
    \bottomrule
\end{tabular}
\end{document}

但请注意，这完全违背了booktabs哲学！所以你也可以使用：

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{array}
\begin{document}
\begin{tabular}{lll}
\firsthline
     Time & Money & Length \\
\hline
\rowcolor{yellow} Contemporary \\
    Sec  &  \$ & inch\\  
    Hour  & cents  & cm \\  
    \hline
\rowcolor{yellow} Ancient \\
    ?  &  Dinar & Yard \\  
    horae  &   Drachma & Palm \\  
    \lasthline
\end{tabular}
\end{document}

Answer 3

您可以使用\specialrule：

\documentclass{article}
\usepackage[table]{xcolor}
\usepackage{booktabs}

\newcommand{\yellowbox}[1]{%
  \specialrule{\lightrulewidth}{\aboverulesep}{0pt}
  \hspace*{-\tabcolsep}%
  \begingroup
  \setlength{\fboxsep}{0pt}%
  \colorbox{yellow}{\hspace{\tabcolsep}\strut #1\hspace{\tabcolsep}}%
  \endgroup
  \hspace*{-\tabcolsep}%
}

\begin{document}

\begin{tabular}{lll}
\toprule
     Time & Money & Length \\
\yellowbox{Contemporary} \\
    Sec  &  \$ & inch \\
    Hour  & cents  & cm \\
\yellowbox{Ancient} \\
    ?  &  Dinar & Yard \\
    horae  &   Drachma & Palm \\
\bottomrule
\end{tabular}

\bigskip

\begin{tabular}{lll}
\toprule
     Time & Money & Length \\
\midrule
\emph{Contemporary} \\
    Sec  &  \$ & inch \\
    Hour  & cents  & cm \\
\midrule
\emph{Ancient} \\
    ?  &  Dinar & Yard \\
    horae  &   Drachma & Palm \\
\bottomrule
\end{tabular}

\end{document}

我提供了该表的两个副本，后者是我更想要的。
