[Tex/LaTex] tabular columns too wide

columnstables

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?

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}

[Tex/LaTex] Tabular with p type columns to fill page width

each tabular column has on the left and right a separation of \tabcolsep which must be substract from the column width if you want it to be of the length \linewidth

\documentclass{article}
\parindent=0pt
\begin{document}

\hrulefill

\begin{tabular}{ | p{\dimexpr 0.25\linewidth-2\tabcolsep} |
                   p{\dimexpr 0.25\linewidth-2\tabcolsep} |
                   p{\dimexpr 0.25\linewidth-2\tabcolsep} |
                   p{\dimexpr 0.25\linewidth-2\tabcolsep} | } \hline
foo & bar & baz & foobar \\\hline
\end{tabular}                

\end{document}

However, using tabularx makes more sense:

\documentclass{article}
\usepackage{tabularx}
\parindent=0pt
\begin{document}

\hrulefill

\begin{tabularx}{\linewidth}{ | X | X | X | X | } \hline
foo & bar & baz & foobar \\\hline
\end{tabularx}                

\end{document}

[Tex/LaTex] latex table too wide

Some comments and observations:

All those \multicolumn{1}{|r|}{...} "wrappers" seem quite unnecessary, especially as you've set the 7 columns to be of type r ("right aligned").
Second, the r column type doesn't allow line breaks in the cells, and that's why the tabular environment is massively too wide. To allow automatic line-breaking, I suggest you change to a tabularx environment, as is shown in code below.
Do give the table a more open "look" by getting rid of all vertical lines. Trust me, they're not needed, and they won't be missed.
Finally, consider centering the cell contents instead of typesetting the flushright (aka raggedleft).

\documentclass[a4paper]{article}
\usepackage[portuguese]{babel} % is this right?
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage{tabularx,ragged2e,booktabs}
\newcolumntype{C}{>{\Centering\arraybackslash\hspace{0pt}}X}
\begin{document}

\noindent% <-- important
\setlength\tabcolsep{3pt} % default: 6pt
\begin{tabularx}{\textwidth}{@{} l *{6}{C} @{}}
\toprule
N ref & Nome da Superfície & Destino da Superfície & Quantidade & Dimensões e precisão & Rugosidade Rz/Ra & Série Norma Ra \\
\midrule

\midrule

\bottomrule
\end{tabularx} 
\end{document}
