Graphics, Figures & Tables ⇒ diagonal line in table (\backslashbox doesn't work fine)

[wolfrain]

Hello there,

in the attachment I got a kindof table I want to generate in Latex file, but yet I cannot find a way to do it.

Basically I have tried this

Code: Select all

\begin{table}
\begin{center}
\begin{tabular}{r|cc}
\backslashbox{i}{j} & 1 & 2 \\\hline
1 & $1$ & $2$ \\
2 & $2$ & $1$ 
\end{tabular} 
\end{center} 
\caption{Prisoners' dilemma} 
\label{tab:prisoners}
\end{table}

and it turns out to be too big in the diagonal-lined box.

Table after compiled.

I want a smaller and compact one as the attachment shows.

This is something I want to make.

====================
One more problem occurs where the diagonal line disappears, although the reserved space is still there.

Am I missing any package without including it in the main file??

thank you,

Hi,

you could use PGF/TikZ:

Code: Select all

\documentclass{article}
\usepackage{tikz}
\usetikzlibrary{matrix,calc}

\begin{document}

\begin{table}[!ht]
\centering
\begin{tikzpicture}
  \matrix (pridil) [%
    matrix of nodes,
    text width=4.1mm,text height=.3cm,
    text badly centered
  ]
  {%
    \null  & 1 & 2 \\
    1 & 1 & 2 \\
    2 & 1 & 2 \\
  };
  \draw[thin,black] (pridil-1-2.south west) -- (pridil-1-3.south east);
  \draw[thin,black] (pridil-2-1.north east) -- (pridil-3-1.south east);
  \draw[thin,black] (pridil-1-1.north west) -- (pridil-1-1.south east);
  \node at ($(pridil-1-1.north west)+(0.5,-0.1)$) {i};
  \node at ($(pridil-1-1.north west)+(0.1,-0.4)$) {j};
\end{tikzpicture}
\caption{Prisoners' dilemma} 
\label{tab:prisoners}
\end{table}

\end{document}

Code: Select all

\backslashbox[-10pt][l]{i}{j} & 1 & 2 \\\hline

use the optional arguments!

Thank you very much for your reply!

It works but unfortunately the end of diagonal line is not connected to the right-angle corner.

Thank you!

Yea, it has become more compact, but still the diagonal line is missing...

then make an _complete_ example, which shows this behaviour!

Code: Select all

\documentclass{article}
\usepackage{slashbox}

\begin{document}

\begin{tabular}{r|cc}
\backslashbox[10pt][l]{i}{j} & 1 & 2 \\\hline
1 & $1$ & $2$ \\
2 & $2$ & $1$
\end{tabular} 

\end{document}

this works!

It's weird... It doesn't appear in my case, although there is no error or warning but 1 Bad Box...

did you view the dvi or pdf output?
And send the complete logfile of the example
