# Table row height, text vertical center and color

So I have the table in the following working example.

I used the solution at Column and row padding in tables but still the text inside each cell is not centered vertically …

Besides, I wanted to give it a fancier look like in Beamer table drop shadow but I don't seem to be able to include \rowcolors{1}{RoyalBlue!20}{RoyalBlue!5} when working with \multicolumn, same for the drop shadow.

\documentclass[ignorenonframetext, xcolor={dvipsnames,table}]{beamer}
\mode<presentation> {
\usetheme{Berkeley}
\usecolortheme{dolphin}

\usepackage{multirow}
\usepackage{pbox}
}

\begin{document}
\begin{frame}
\begin{center}
{\small
\begin{tabular}{l|c|c|c|}
\multicolumn{1}{r}{}
& \multicolumn{1}{c}{\textbf{\pbox{20cm}{Tissue-specific\\penetrance}}}
& \multicolumn{1}{c}{\textbf{\pbox{20cm}{Ubiquitous\\penetrance}}}
& \multicolumn{1}{c}{}\\
\cline{2-4}
\textbf{\pbox{20cm}{Tissue-specific\\expression}}
& \textit{\pbox{20cm}{CLASS 1\\12 genes}}
& \textit{\pbox{20cm}{CLASS 4\\8 genes}}
& \textcolor{green!70!black}{20 genes}\\
\cline{2-4}
\textbf{\pbox{20cm}{Ubiquitous\\expression}}
& \textit{\pbox{20cm}{CLASS 3\\32 genes}}
& \textit{\pbox{20cm}{CLASS 2\\20 genes}}
& \textcolor{pink}{52 genes}\\
\cline{2-4}
\cline{2-4}
& \textcolor{red!70!black}{44 genes}
& \textcolor{RoyalBlue}{28 genes}
& \textbf{\pbox{20cm}{72 genes}}\\
\cline{2-4}
\end{tabular}
}
\end{center}
\end{frame}
\end{document}

• A few notes beforehand: The \bgroup/\egroup is not needed as the center environment itself already groups its content. The use of \small is wrong. It is a switch so you don’t use \small{<something>} but (to keep it local) {\small <something>}. In this case, though, you could just add \small before \begin{tabular} and it makes the whole table in that size. – Qrrbrbirlbel Jun 24 '13 at 1:14
• Thanks for the suggestions! I have just made the changes and edited the question, but now the table looks much more condensed... how could I specify the row height so that the text remains vertically aligned? and how could I specify the color for each row (and the drop shadow)? Many thanks again! – DaniCee Jun 24 '13 at 15:12
• anyone can help? I just need to specify row height... any idea??? – DaniCee Jun 24 '13 at 17:09
• no one?? isn't there any way to specify row height? – DaniCee Jun 24 '13 at 20:56

I'd suggest "cals" tables:

\documentclass[ignorenonframetext, xcolor={dvipsnames,table}]{beamer}
\mode<presentation> {
\usetheme{Berkeley}
\usecolortheme{dolphin}
}
\usepackage{cals}

\iffalse
\makeatletter
\let\olderow=\erow
\def\erow{\ht\cals@current@row=1.2cm \olderow}
\let\oldbrow=\brow
\def\browI{\oldbrow\def\cals@bgcolor{RoyalBlue!20}\let\brow=\browII}
\def\browII{\oldbrow\def\cals@bgcolor{RoyalBlue!5}\let\brow=\browI}
\let\brow=\browI
\fi

\begin{document}
\begin{frame}
\begin{center}
\small
\makeatletter
\begin{calstable}

\colwidths{{27mm}{27mm}{28mm}{20mm}}
\brow
\cell{}
\cell{\bfseries Tissue-specific\\penetrance}
\cell{\bfseries Ubiquitous\\penetrance}
\cell{}
\erow
\brow
\cell{\bfseries Tissue-specific\\expression}
\cell{CLASS 1\\12 genes}
\cell{CLASS 4\\8 genes}
\cell{\textcolor{green!70!black}{20 genes}}
\erow
\brow
\cell{\bfseries Ubiquitous\\expression}
\cell{CLASS 3\\32 genes}
\cell{CLASS 2\\20 genes}
\cell{\textcolor{pink}{52 genes}}
\erow
\brow
\cell{}
\cell{\textcolor{red!70!black}{44 genes}}
\cell{\textcolor{RoyalBlue}{28 genes}}
\cell{\bfseries 72 genes}
\erow
\end{calstable}
\end{center}
\end{frame}
\end{document}


The table looks good even without tuning:

If you want to experiment with row colors and height, change "iffalse" to "iftrue". I have no experience with drop shadows, therefore can't recommend anything.

This is sort of in between the no-space in cells of your question and the space found in olpa's answer.

\documentclass[ignorenonframetext, xcolor={dvipsnames,table}]{beamer}
\mode<presentation> {
\usetheme{Berkeley}
\usecolortheme{dolphin}
\usepackage{multirow}
\usepackage[oldsyntax]{stackengine}
}
\begin{document}
\begin{frame}
\begin{center}
{\small
\Sstackgap=2pt%
\def\stackalignment{l}%
\begin{tabular}{l|c|c|c|}
\multicolumn{1}{r}{}
&\multicolumn{1}{c}{\textbf{\stackanchor[1pt]{Tissue-specific}{penetrance}}}
& \multicolumn{1}{c}{\textbf{\stackanchor[1pt]{Ubiquitous}{penetrance}}}
& \multicolumn{1}{c}{}\\
\cline{2-4}
\textbf{\stackanchor[1pt]{Tissue-specific}{expression}}
& \textit{\stackanchor{CLASS 1}{12 genes}}
& \textit{\stackanchor{CLASS 4}{8 genes}}
& \textcolor{green!70!black}{20 genes}\\
\cline{2-4}
\textbf{\stackanchor[1pt]{Ubiquitous}{expression}}
& \textit{\stackanchor{CLASS 3}{32 genes}}
& \textit{\stackanchor{CLASS 2}{20 genes}}
& \textcolor{pink}{52 genes}\\
\cline{2-4}
\cline{2-4}
& \textcolor{red!70!black}{44 genes}
& \textcolor{RoyalBlue}{28 genes}
& \textbf{72 genes}\\
\cline{2-4}
\end{tabular}
}
\end{center}
\end{frame}
\end{document}


[EDIT: This MWE uses obsolete stackengine syntax for setting stackgap lengths (e.g., \Sstackgap=1ex), which prevented scalable lengths from scaling under a fontsize change. Version 2 of the package (submitted 7/11/13) remedies the problem with a small syntax change.]
