I've got following table which is almost what I wanted to have. But it would be much better if cells with text would be aligned vertical (only vertical) and cells with -- would be aligned vertical & horizontal.
Does anyone has a suggestion on that issue?
Here is my table:
\documentclass[10pt,a4paper]{scrreprt}
\usepackage{classicthesis-ldpkg}
\usepackage{multicol}
\usepackage{multirow}
\usepackage{rotating}
\usepackage[table]{xcolor}
\usepackage{booktabs}
\usepackage{lscape}
\newcolumntype{R}[1]{>{\raggedright\arraybackslash}p{#1}}
\begin{document}
\begin{landscape}
\begin{tabular}{R{4cm}R{4cm}R{4cm}R{4cm}} %<--- damit geht es jetzt auch ;)
\toprule
\multicolumn{1}{c}{\textbf{Cluster 1}} & \multicolumn{1}{c}{\textbf{Cluster 2}} & \multicolumn{1}{c}{\textbf{Cluster 3}} & \multicolumn{1}{c}{\textbf{Cluster 4}} \\
\midrule
\rowcolor[gray]{.9} Canada, France, Germany & Italy, Japan, United Kingdom, United States & -- & --\\
Austria, Belgium, Netherlands, Switzerland & -- & Luxembourg & --\\
\rowcolor[gray]{.9} Finland, Iceland, Norway, Sweden & Denmark, Ireland & -- & --\\
-- & Estonia, Hungary & Czech Republic, Slovenia & Poland, Slovak Republic \\
\rowcolor[gray]{.9} Greece, Portugal, Spain & -- & -- & -- \\
New Zealand & -- & Australia, Korea, Turkey & Israel \\
\bottomrule
\end{tabular}
\end{landscape}
\end{document}
