表格/表格行间距

Question

我正在尝试对一个交替行的表格进行文本处理。它可以工作，但是行之间有一个非彩色的间隙/间距，所以看起来很奇怪：

以下是上面示例的代码：

% !TEX TS-program = pdflatex
% !TEX encoding = UTF-8 Unicode

\documentclass[a4paper, 11pt]{article}

\usepackage[utf8]{inputenc}

\usepackage{graphicx}
\usepackage{booktabs}
\usepackage[table]{xcolor}



\begin{document}

\begin{table}[htbp]
  \caption{My Title}
  \rowcolors{2}{gray!20}{white}
  \setlength{\tabcolsep}{0.2cm}
  \centering\vspace{3pt}
  \begin{tabular}{p{2.5cm}>{\raggedright\arraybackslash}p{2.5cm}}\toprule
    \textbf{Type} & \textbf{Name} \\\midrule
    Animal & Monkey \\\midrule
    Animal & Lion \\\midrule
    Fruit & Apple \\
    Fruit & Banana \\\bottomrule
  \end{tabular}
\end{table}
\end{document}

---

有谁知道如何解决这个问题，而无需对软件包/标记进行太多更改？是否有一些参数需要调整？

非常感谢，并致以最诚挚的问候，

Answer 1

使用\hline而不是\midrule：

\documentclass[a4paper, 11pt]{article}

\usepackage[utf8]{inputenc}

\usepackage{graphicx}
\usepackage{booktabs}
\usepackage[table]{xcolor}



\begin{document}

\begin{table}[htbp]
  \caption{My Title}
  \rowcolors{2}{gray!20}{white}
  \setlength{\tabcolsep}{0.2cm}
  \centering\vspace{3pt}
  \begin{tabular}{p{2.5cm}>{\raggedright\arraybackslash}p{2.5cm}}\hline
    \textbf{Type} & \textbf{Name} \\
    \hline
    Animal & Monkey \\
    \hline
    Animal & Lion \\
    \hline
    Fruit & Apple \\
    \hline
    Fruit & Banana \\
    \hline
  \end{tabular}
\end{table}
\end{document}

输出：

Answer 2

这是因为在规则（、和等）之前和之后booktabs引入了\aboverulesep和。没有用颜色绘制这个空间，所以我们得到了间隙。可以通过在上方和下方绘制与行相同的颜色的高度来防止这种情况。\belowrulesep\toprule\bottomrule\midrule\rowcolors\hrule\aboverulesep\belowrulesep

% !TEX TS-program = pdflatex
% !TEX encoding = UTF-8 Unicode

\documentclass[a4paper, 11pt]{article}

\usepackage[utf8]{inputenc}

\usepackage{graphicx}
\usepackage{booktabs}
\usepackage[table]{xcolor}

\newcommand*{\belowrulesepcolor}[1]{%
  \noalign{%
    \vspace{-\belowrulesep}
    \bgroup
      \color{#1}%
      \hrule height\belowrulesep
    \egroup
  }%
}
\newcommand*{\aboverulesepcolor}[1]{%
  \noalign{%
    \bgroup
      \color{#1}%
      \hrule height\aboverulesep
    \egroup
    \vspace{-\aboverulesep}
  }%
}



\begin{document}

\begin{table}[htbp]
  \caption{My Title}
  \rowcolors{2}{gray!20}{white}
  \setlength{\tabcolsep}{0.2cm}
  \centering\vspace{3pt}
  \begin{tabular}{p{2.5cm}>{\raggedright\arraybackslash}p{2.5cm}}\toprule
    \textbf{Type} & \textbf{Name} \\\midrule
    Animal & Monkey \\\midrule
    \belowrulesepcolor{gray!20}
    Animal & Lion \\
    \aboverulesepcolor{gray!20}\midrule
    Fruit & Apple \\
%    \belowrulesepcolor{gray!20}   %% not needed since there is no midrule.
    Fruit & Banana \\\aboverulesepcolor{gray!20}
    \bottomrule
  \end{tabular}
\end{table}
\end{document}

但更好的方法是放弃这些，\midrule因为行是用颜色突出显示的

Answer 3

这是我最终选择的解决方案的代码：

% !TEX TS-program = pdflatex
% !TEX encoding = UTF-8 Unicode

\documentclass[a4paper, 11pt]{article}

\usepackage[utf8]{inputenc}
\usepackage{graphicx}
\usepackage{booktabs}
\usepackage[table]{xcolor}

\setlength{\aboverulesep}{0pt}
\setlength{\belowrulesep}{0pt}
\renewcommand*{\arraystretch}{1.2}

\begin{document}

\begin{table}[htbp]
  \caption{My Title}
  \rowcolors{2}{gray!20}{white}
  \setlength{\tabcolsep}{0.2cm}
  \centering\vspace{3pt}
  \begin{tabular}{p{2.5cm}>{\raggedright\arraybackslash}p{2.5cm}}\toprule
    \textbf{Type} & \textbf{Name} \\\midrule
    Animal & Monkey \\\midrule
    Animal & Lion \\\midrule
    Fruit & Apple \\
    Fruit & Banana \\\bottomrule
  \end{tabular}
\end{table}
\end{document}
