如何改变表格中虚线的宽度？

我需要画几个一个表格中不同宽度的虚线，但我不知道该怎么做。

我知道如何使用包绘制单条虚线arydshln，但如何设置这些虚线的宽度？ \setheight\arrayrulewidth{1pt}仅适用于整个表格，而不适用于特定的单条线。

这是代码。

\documentclass{article}
\usepackage{arydshln}

\begin{document}
% \setheight\arrayrulewidth{1pt} % works for the whole table
\begin{tabular}{cc}
  \hdashline % need set to 0.8pt
  a & b\\
  \hdashline % need set to 0.6pt
\end{tabular}
\end{document}

我的解决方案

我使用包ehhline来dashrule得到我想要的东西。

\documentclass{article}
\usepackage{colortbl}
\usepackage{dashrule}
\usepackage{ehhline}
\usepackage{arydshln}
\newcommand\cdl[2]{\leaders\hbox{\textcolor{#1}{\hdashrule{0.4mm}{#2}{0.2mm 0.2mm}}}\hfil}
\newcommand\crs[2]{\leaders\hbox{\textcolor{#1}{\rule{0.1pt}{#2}}}\hfil}

\begin{document}
\begin{tabular}{|c|c|}
\hhline{
  !{\cdl{red}{1pt}}
  !{\crs{red}{1pt}}
}
test some thing & test\\
\hhline{
  !{\cdl{blue}{4pt}}
  !{\crs{blue}{4pt}}
}
  test some thing & test\\
\hhline{
  !{\cdl{blue}{4pt}}
  !{\crs{blue}{4pt}}
}
  test some thing & test\\
\hhline{
  !{\cdl{blue}{4pt}}
  !{\crs{blue}{4pt}}
}
\end{tabular}
\end{document}

虚线

仍未解决

但还有一个问题：如何绘制垂直虚线不同颜色和宽度

答案1

{NiceTabular}在 (2020-05-08 ≥ 4.0)的环境下，你可以使用数组下nicematrix创建的 PGF/Tikz 节点用 Tikz 绘制任何你想要的规则。nicematrix

\documentclass{article}
\usepackage{nicematrix,tikz}

\begin{document}
\tikzset
  {  
    dashed 1/.style = 
      {
        red ,
        dash pattern = on 2pt off 3pt ,
        line width = 1 pt 
      } ,
    dashed 2/.style = 
      {
        blue ,
        dash pattern = on 1pt off 1pt ,
        line width = 2pt 
      }
  }

\begin{NiceTabular}{|ccc|}
\hline
text text & text text & text text \\
text text & text text & text text \\
text text & text text & text text \\
text text & text text & text text \\
text text & text text & text text \\
\hline
\CodeAfter
\begin{tikzpicture}
\draw [dashed 1] (1-|2) -- (6-|2) (2-|1) -- (2-|4) ;
\draw [dashed 2] (1-|3) -- (6-|3) (4-|1) -- (4-|4) ;
\end{tikzpicture}
\end{NiceTabular}
\end{document}

第一个代码的输出

使用较新版本nicematrix（2022-07-28 的 6.12 版），还可以定义字母（用于垂直规则）和命令（用于水平规则）以使用我们想要的任何 Tikz 样式绘制规则。

\documentclass{article}
\usepackage{nicematrix,tikz}

\begin{document}
\NiceMatrixOptions
  {  
    custom-line = 
      {
        letter = I , 
        command = DashedLine ,
        tikz = 
          {
            red ,
            dash pattern = on 2pt off 3pt ,
            line width = 1 pt 
          } ,
        total-width = 1 pt % space reserved for the rule
      } ,
    custom-line = 
      {
        letter = J ,
        command = DashedLineBis ,
        tikz = 
          {
            blue ,
            dash pattern = on 1pt off 1pt ,
            line width = 2pt 
          } ,
        total-width = 2 pt 
      }
  }

\begin{NiceTabular}{|cIcJc|}
\hline
text text & text text & text text \\
\DashedLine
text text & text text & text text \\
text text & text text & text text \\
\DashedLineBis
text text & text text & text text \\
text text & text text & text text \\
\hline
\end{NiceTabular}

\end{document}

第二段代码的输出

答案2

我对领导者没有太多经验，所以唯一能让它发挥作用的方法是先测量表格的宽度。为此，我创建了环境mytabular。

我没有实现双虚线或虚线\cline。

\documentclass{article}
\usepackage{environ}

\newsavebox{\mybox}

\newcommand{\dashline}[3]% #1 = dash, #2 = spacing, #3 = height
{\noalign{\hbox to \wd\mybox{\leaders\hbox to #2{\hss\rule{#1}{#3}\hss}\hfill}}}

\newcommand{\gobbleline}[3]{\noalign{\hrule}}

\NewEnviron{mytabular}[1]% #1 = tabular parameters
{\savebox{\mybox}{\let\dashline=\gobbleline% disable \dashline
  \begin{tabular}{#1}
    \BODY
  \end{tabular}}% measure width
  \begin{tabular}{#1}
    \BODY
  \end{tabular}}

\begin{document}
\begin{mytabular}{cc}
\dashline{0.8pt}{4pt}{1pt}
  a & b \\
\dashline{0.4pt}{4pt}{0.5pt}
\end{mytabular}
\end{document}

或者，可以重新定义表格环境，但这将花费旧环境的两倍时间。

\documentclass{article}
\usepackage{environ}

\newsavebox{\mybox}

\newcommand{\dashline}[3]% #1 = dash, #2 = spacing, #3 = height
{\noalign{\hbox to \wd\mybox{\leaders\hbox to #2{\hss\rule{#1}{#3}\hss}\hfill}}}

\newcommand{\gobbleline}[3]{\noalign{\hrule}}

\let\oldtabular=\tabular
\let\oldendtabular=\endtabular

\RenewEnviron{tabular}[1]% #1 = normal tabular parameters
{\savebox{\mybox}{\let\dashline=\gobbleline% disable \dashline
  \oldtabular{#1}
    \BODY
  \oldendtabular}% measure width
  \oldtabular{#1}
    \BODY
  \oldendtabular}

\begin{document}
\begin{tabular}{cc}
\dashline{0.8pt}{4pt}{1pt}
  a & b \\
\dashline{0.4pt}{4pt}{0.5pt}
\end{tabular}
\end{document}
