[michael_b]

Hello everybody

i have to create a chart in latex and hope that you can help me.

the chart has to look like:

Hi micheal_b,

The way I would do it would be to imagine that every square on the paper in your example represents a column or row then only put in lines when appropriate.

You will need to use \multicolumn and \cline commands. I'm busy at the moment so have only done a small example to get you started. If you don't understand anything please ask.

Code: Select all

\documentclass{article}
\usepackage{slashbox,multirow}
\begin{document}
\begin{tabular}{|ccc|}
\hline
\multicolumn{1}{|c|}{A}&&\\
\cline{1-1}
&$x_{12}$&\\
&&\\
\hline
\multicolumn{3}{|c|}{\multirow{3}{*}{\backslashbox{20}{20}}}\\ && \\ &&\\
\hline
\end{tabular}
\end{document}

I found the slashbox package through google and it can be downloaded here. It isn't perfect but is a good start

hi php1ic!

thank you for the quick answer.

i have no problems to add new boxes in one way. But how can i add new splits?

My code looks now like that:

Code: Select all

\documentclass{article}
\usepackage{slashbox,multirow}
\begin{document}
\begin{tabular}{|ccc|}
\hline
\multicolumn{1}{|c}{}&&\\
&$B_1$&\\
&&\\
\hline
\hline
\multicolumn{1}{|c|}{2}&&\\
\cline{1-1}
&$x_{11}$&\\
&&\\
\hline
\multicolumn{1}{|c|}{2}&&\\
\cline{1-1}
&$x_{21}$&\\
&&\\
\hline
\multicolumn{1}{|c|}{1}&&\\
\cline{1-1}
&$x_{31}$&\\
&&\\
\hline
\multicolumn{1}{|c}{}&&\\
&$10$&\\
&&\\
\hline
\end{tabular}
\end{document}

Additionally, is there a possibility to pick e.g. the x_11 to the head of the box so that the x_11 are beside the number?

I assume by splits you mean columns. To do that you need to put more arguments when you start the tabular environment

Code: Select all

\begin{tabular}{|ccc|ccc|ccc|}

each letter 'c' represents a column containing centered text (r - right aligned, l - left). The code below almost reproduces the table you want but maths mode cannot be used with \multirow so you may want to continue constructing the table by extending the code you posted.

Code: Select all

\begin{tabular}{cc|cc|cc|ccc}
&&\multicolumn{2}{|c|}{B{\tiny 1}}&\multicolumn{2}{|c|}{B{\tiny 2}}&\multicolumn{3}{|c}{a{\tiny i}}\\
\hline
\multicolumn{2}{c|}{\multirow{2}{*}{A{\tiny 1}}}&\multicolumn{1}{|c|}{1}&$x_{11}$&\multicolumn{1}{|c|}{2}&$x_{12}$&\multicolumn{3}{c}{\multirow{2}{*}{ 10 }}\\
\cline{3-3}\cline{5-5}
&&&&&&\\
\hline
\multicolumn{2}{c|}{\multirow{2}{*}{A{\tiny 2}}}&\multicolumn{1}{|c|}{3}&$x_{21}$&\multicolumn{1}{|c|}{4}&$x_{22}$&\multicolumn{3}{c}{\multirow{2}{*}{ 10 }}\\
\cline{3-3}\cline{5-5}
&&&&&&\\
\hline
\multicolumn{2}{c|}{\multirow{2}{*}{b{\tiny i}}}&\multicolumn{2}{c|}{\multirow{2}{*}{10}}&\multicolumn{2}{c|}{\multirow{2}{*}{10}}&\multicolumn{3}{c}{\multirow{2}{*}{\backslashbox{20}{20}}}\\
&&&&&\\
\end{tabular}

to put x_11 at the top for your example, simply move it up one cell ie

Code: Select all

\hline
\multicolumn{1}{|c|}{2}&$x_{11}$&\\
\cline{1-1}
&&\\
&&\\
\hline

Yes you are right, i mean columns. Well thank you very much for your help. I have extend the code for another example and it looks great.
