# Center subcaption-based tabulars in a beamer frame

I have several tabulars side-by-side using the subcaption package in beamer:

However, as you can see, they are not quite centered.

How can I center the tabulars, so that tabular RAID5 isn't on the very right and RAID0 hasn't too much space on the left side?

This is my current code:

\documentclass{beamer}
\usepackage{subcaption}

\begin{document}
% ...
\frame{\frametitle{RAID-Types}
\begin{table}[!htb]
\subcaptionbox{RAID0}[.25\linewidth]{%
\begin{tabular}{|c|c|c|}
\hline
0&1&2\\
\hline
3&4&5\\
\hline
6&7&8\\
\hline
\end{tabular}}%
\subcaptionbox{RAID1}[.25\linewidth]{%
\begin{tabular}{|c|c|c|}
\hline
0&0&0\\
\hline
1&1&1\\
\hline
2&2&2\\
\hline
\end{tabular}}%
\subcaptionbox{RAID5}[.25\linewidth]{%
\begin{tabular}{|c|c|c|}
\hline
0&1&P(0+1)\\
\hline
2&P(2+3)&3\\
\hline
P(4+5)&4&5\\
\hline
\end{tabular}}%
\caption{RAID-Types. Each column represents one disk. Each row is a block level.}
\end{table}
}


As I mentioned in my answer to Subcaption with Beamer, it's better not to use caption/subcaption with beamer; you can use subfig, with the caption=false option, instead:

\documentclass{beamer}
\usepackage[caption=false]{subfig}

\begin{document}

\begin{frame}
\frametitle{RAID-Types}
\begin{table}
\subfloat[RAID0]{%
\begin{tabular}{|c|c|c|}
\hline
0&1&2\\
\hline
3&4&5\\
\hline
6&7&8\\
\hline
\subfloat[RAID1]{%
\begin{tabular}{|c|c|c|}
\hline
0&0&0\\
\hline
1&1&1\\
\hline
2&2&2\\
\hline
\subfloat[RAID5]{%
\begin{tabular}{|c|c|c|}
\hline
0&1&P(0+1)\\
\hline
2&P(2+3)&3\\
\hline
P(4+5)&4&5\\
\hline
\end{tabular}}%
\caption{RAID-Types. Each column represents one disk. Each row is a block level.}
\end{table}
\end{frame}

\end{document}


• Thanks, that works better :). How can I add a newline/new row of floats, without destroying the first row? E.g. If I add another subfloat called RAID4, then the first row contains RAID0 and RAID1 only and RAID5 goes to row2. I want to keep the structure of row1, however. EDIT: I got it. Adding \bigskip and newlines after the first three floats. Aug 5, 2014 at 17:59
