# How do I fit this table to the frame in Beamer?

\documentclass{Beamer}

\begin{document}

\begin{table}
\begin{tabular}{l l l}
\toprule
Band &   &  \\
\hline
Total stop band & No propagation possible & All of the incident field is reflected back  \\ % inserting body of the table
Partial stop band & Propagation possible for some directions & Some/all energy converted to Bloch waves  \\
Pass band & Propagation possible in all directions & Some/all energy converted to Bloch waves \\
\bottomrule
\end{tabular}
\caption{Table caption}
\end{table}

\end{document}

• Please create a minimal working example (MWE) that will compile. Your code does not compile. – Sverre May 21 '15 at 12:36
• You have two choices: you can shrink it or break it into smaller chunks. See tex.stackexchange.com/questions/38177/… – John Kormylo May 21 '15 at 14:25
• If a table must be squeezed to fit on a slide, it may have too much information for your talk. Your audience may be trying to read it just when you want them listening to you. Perhaps you can summarize it and refer them to a place where they can read the details. – Ethan Bolker May 21 '15 at 18:18
• I doubt this is the case, but quite often, the microtype package can save some space by using micro-typographic changes (slight adjustments of the kernel, of the space, etc.) – Clément May 21 '15 at 19:43

You have two possibilities (as stated John Kormylo in his comment):

1. reduce font size to tiny
2. reduce font size to small and instead tabular use for example tabularx which broke lines and reduce \tobcolsep to 3pt.

MWE:

\documentclass{Beamer}
\usepackage{booktabs,tabularx}
\newcolumntype{L}{>{\raggedright\arraybackslash}X}

\begin{document}
\begin{frame}
\begin{table}\tiny
\begin{tabular}{@{}l l l@{}}
\toprule
Band &   &  \\
\midrule
Total stop band
& No propagation possible
& All of the incident field is reflected back   \\
Partial stop band
& Propagation possible for some directions
& Some/all energy converted to Bloch waves      \\
Pass band
& Propagation possible in all directions
& Some/all energy converted to Bloch waves      \\
\bottomrule
\end{tabular}
\caption{Table caption: case 1}
\end{table}

\begin{table}
