I want to draw a double cline in a table where the first column is multirow With double \hline I can draw a full double horizontal line but double \cline{i-j} seems to have the same effect with single \cline. Is there any other special command to do that?

Thank you

AFAIK the \cline does not add vertical space by itself, therefore the two are just printed over each other. The booktabs package, which I can recommend greatly in general for all tables, defines therefore the \morecmidrules macro:

% \cline is now \cmidrule
\cmidrule{1-2}\morecmidrules\cmidrule{1-2}

However, the booktabs manual says that double lines are evil and should not be used at all....

  • Thanks, good hint but now I have a different problem. The vertical lines-borders of the table are broken. Please see the image: img189.imageshack.us/img189/8383/brokentable.png

    @Vasilis: Mmm, I can't tell how to fix that. All what I know is that vertical lines are also considered as evil by the booktabs manual ;-) My advice is to avoid them and most horizontal lines. Only do a \toprule on top and a \bottomrule at the bottom, plus a single \cmidrule where you wanted the double rule. This design is new to most people which know tables only from M$ Word, but believe me, it looks better!

    @Vasilis. As Martin says, the table you've linked to should not have vertical lines.

  • Indeed it looks better without vertical lines.

  • There is however a tradition that double horizontal lines mean summation. So I guess yes they are evil but sometimes tradition is tradition... :)

use package hhline, available with any TeX distribution:

\documentclass[a4paper]{article}
\usepackage{hhline}
\begin{document}

\begin{tabular}{ccc}\hhline{=~~}
 foo & bar & baz  \\\hhline{~=~}
 foo & bar & baz  \\\hhline{~~=} 
\end{tabular}

\end{document}

  • Simple, and works great! But is there a way to let the vertical lines reach the additional hline? See this example: dl.dropboxusercontent.com/u/78851488/Bild1.png I want the horizontal double line at the bottom to look like the vertical double line in the top part of the picture.

  • read the manual of the package hhline. There is an example

Put

\noalign{\vskip\doublerulesep
         \vskip-\arrayrulewidth}

between \clines.

  • That almost works perfectly, except that I have a vertical line on the very left which I would want to stay contiguous (because that is a merged cell).

  • Is not it the same as for double \hline? (If so, you are barking at a wrong tree…)

  • Maybe it was not clear what I meant. I added an own answer which shows this, and my solution.

    This makes the gap very small. The same spacing as for double \hline is achieved by: \noalign{\vskip\arrayrulewidth \vskip\doublerulesep}. The \arrayrulewidth is the width of the line and the \doublerulesep is the size of the gap between the two lines.

The solution by Ilya Zakharevich:

... \\ \cline{2-4}
\noalign{\vskip\doublerulesep
         \vskip-\arrayrulewidth} \cline{2-4}
...

results in this for me: noalign ilya var1

Note that I have a vertical line on the very left which I would want to stay contiguous, so this is not so nice.

So my solution:

... \\ \cline{2-4}
\noalign{\vskip-2\tabcolsep \vskip-3\arrayrulewidth \vskip\doublerulesep}
\\ \cline{2-4}
...

This adds another row (\\) and then tries to reduce the space of the row (I probably messed up the calculation...).

var2

I came up with another variant:

... \\ \cline{2-4}
\multicolumn{4}{|c}{\phantom{x}}
\vspace{-2\tabcolsep}\vspace{-3\arrayrulewidth}\vspace{\doublerulesep}
\\ \cline{2-4}
...

Which results in: var3

In the environment {NiceTabular} of nicematrix, you have a command \Hline which draws horizontal rules excepted in the blocks (created by the command \Block). With \Hline\Hline, you draw a double horizontal rule which potentially do not extend on the whole array. Moreover, you can use the key hvlines to draw all the rules and add \Hline\Hline only where you wish.

With Albert's example:

\documentclass{article}

\usepackage{nicematrix}

\begin{document}

\begin{NiceTabular}{cccc}[hvlines]
$T_{\omega}$ ([sec]) & $T_s$ ([sec]) & Distribution & WER[\%] \\
\Hline\Hline
\Block{6-1}{}
40 (0.4)  & \Block{4-1}{} 5 (0.05) & Uniform & 13.9 \\
          &          & Triangle & 13.8 \\
          &          & Hamming & 13.8 \\
          &          & Gauss $\sigma = 0.4$ & 13.8 \\
\Hline\Hline
          & \Block{2-1}{}4 (0.04) & Uniform & 13.7 \\
          &          & Triangle & 13.7 \\
\Hline\Hline
\Block{3-1}{}
100 (1.0) & \Block{3-1}{}5 (0.05) & Uniform & 13.6 \\
          &          & Hamming & 1.7 \\
          &          & Gauss $\sigma = 0.4$ & 13.7 \\
\end{NiceTabular}

\end{document}

You need several compilations (because nicematrix uses PGF/Tikz nodes under the hood). Output of the above code
