# tabular columns too wide

I want to fit the following table on a beamer slide.

\begin{tabular}{|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|c|}
A & B & C & D & E & F & G & H & I & J & K & L & M & N & O & P & Q & R & S & T & U & V & W &   X & Y & Z \\
G & T & U & J & C & P & L & D & O & R & Y & W & X & Z & F & I & V & Q & S & K & A & N & E & M & H & B \\
\end{tabular}


However it won't fit, because there is too much space in a single column. If the borders were to perfectly enclose the letters, it would fit.

Does anyone know how to do that?

• You can use @{}c@{} instead of c to remove the cell spacing. Also try to set \tabcolsep to 0pt. – Martin Scharrer Dec 14 '11 at 14:28
• have you considered to redefine \tabcolsep, the separation between columns. Also you could delete it completely with {@{}c@{}...}. A smaller font would probably be better. Maybe using tabularx you can squeeze it to textwidth. A working example would be good. Some beamer themes have a side bar and some don't... – Martin H Dec 14 '11 at 14:29
• @MartinScharrer's suggestion should work just fine for you. Note that you can use the * notation to make things a little easier on you. You won't have to change 26 occurences. Just go |@{}c@{}*{25}{|@{}c@{}}|. – Roelof Spijker Dec 14 '11 at 14:35
• The @{}c@{} method works! The result fits, but a little bit of spacing would be ok. Is there a way to do a little bit of spacing and keep the *-notation? – Ben Ruijl Dec 14 '11 at 15:49

Modify the length \tabcolsep to compress the table horizontally.

\documentclass[smaller]{beamer}
\usepackage[T1]{fontenc}
\usepackage{fix-cm}

\setlength{\tabcolsep}{2pt}

\begin{document}
\begin{frame}
\begin{tabular}{|*{26}{c|}}
A & B & C & D & E & F & G & H & I & J & K & L & M & N & O & P & Q & R & S & T & U & V & W &   X & Y & Z \\
G & T & U & J & C & P & L & D & O & R & Y & W & X & Z & F & I & V & Q & S & K & A & N & E & M & H & B \\
\end{tabular}
\end{frame}
\end{document}

• How can I, if I even can, use this hint with tabular* environment? I've tried structure \begin{tabular*}{\textwidth}{cccc} and table was narrower than text width but \hlines were exceeding the table (they have full width). – Crowley Feb 1 '12 at 11:00
• @Crowley a tabular* or tabularx have to have a stretchable column, you are not giving it any, so the environment is confused :-) – yo' Jul 14 '17 at 20:29
\documentclass{beamer}
\begin{document}
\begin{frame}
\resizebox{\linewidth} {\height}{%
\setlength\tabcolsep{2pt}%
\begin{tabular}{|*{26}{c|}}
A & B & C & D & E & F & G & H & I & J & K & L & M & N & O & P & Q & R & S & T & U & V & W &   X & Y & Z \\
G & T & U & J & C & P & L & D & O & R & Y & W & X & Z & F & I & V & Q & S & K & A & N & E & M & H & B \\
\end{tabular}}
\end{frame}
