A friend is trying to make some auto-generated bingo boards, and LaTeX seems like an obvious choice - nothing fancy, just a 5x5 table with square cells, centered text, and line wrapping if necessary. After some searching, I'm at a bit of a loss on setting the vertical height of cells, though. How can I do this?

Given the length of the terms to put in the squares (e.g. "Speech Language Pathologist") I don't think it's reasonable to go for anything but a full sheet of letter paper. (They'll be printed, special paper would be a pain, and two on a sheet is pretty small for that.) Otherwise there aren't really any hard formatting requirements - a legible size, and might as well fill the page as long as you've got it. I'm sure I can adjust details, in any case.

Greetings, and welcome to TeX.SE! Please be a bit more specific about some of your document parameters, such as the size of the sheet of paper and the size of the textblock. Mentioning any requirements regarding fonts (font type, font size) would also be helpful. –  Mico Mar 28 '12 at 3:06

Randomly Generating the Nodes:

Here is a version that randomly generated the nodes using that random number generator built into pgf using the algorithm:

  • Column B contains numbers 1 - 15
  • Column I contains numbers 16 - 30
  • Column N contains numbers 31 - 45
  • Column G contains numbers 46 - 60
  • Column O contains numbers 61 - 75

enter image description here

Further Enhancements:

  • Not sure if duplicated numbers are allowed in a column, if not then this can be enhanced to loop if a previously used number is generated
  • Add a fancy border and label the columns: B, I, N, G, O

Code:

\documentclass{article}
\usepackage{xstring}
\usepackage{tikz}
\usetikzlibrary{calc}

%    Column B contains numbers 1 - 15
%    Column I contains numbers 16 - 30
%    Column N contains numbers 31 - 45
%    Column G contains numbers 46 - 60
%    Column O contains numbers 61 - 75

\def\NumOfColumns{5}%
\def\Sequence{1/A/1/15, 2/B/16/30, 3/C/31/45, 4/D/46/60, 5/E/61/71}%

\newcommand{\Size}{2.5cm}
\tikzset{Square/.style={
    inner sep=0pt,
    text width=\Size, 
    minimum size=\Size,
    draw=black,
    fill=yellow!20,
    align=center,
    }
}

\begin{document}
\begin{tikzpicture}[draw=black, ultra thick, x=\Size,y=\Size]
    \foreach \row/\rowLetter/\MinNumber/\MaxNumber in \Sequence{%
        \foreach \col/\colLetter/\MinNumber/\MaxNumber in \Sequence {%
            \pgfmathtruncatemacro{\value}{\col+\NumOfColumns*(\row-1)}
            \def\NodeText{\pgfmathparse{random(\MinNumber,\MaxNumber)}\pgfmathresult}
            \pgfmathsetmacro{\ColRowProduce}{\col*\row}
            \IfEq{\ColRowProduce}{9}{% If is center square
                \node [Square] at ($(\col,-\row)-(0.5,0.5)$) {\Huge Free Space};
            }{
                \node [Square] at ($(\col,-\row)-(0.5,0.5)$) {\Huge \NodeText};
            }
        }
    }
\end{tikzpicture}
\end{document}

Manually Specifying the Nodes:

I am not sure how you want to set the contents of each cell to be specified, so I provided individual \Node<col><row> macros that you can fill in. If there is an algorithm for choosing those then that too can be automated.

The following uses TikZ nodes. You can change the setting of \Size to specify the length of the side of the square.

enter image description here

Code:

\documentclass{article}
\usepackage{xstring}
\usepackage{tikz}
\usetikzlibrary{calc}

\newcommand{\Size}{2.5cm}% Adjust size of square as desired

\def\NumOfColumns{5}%
\def\Sequence{1/A, 2/B, 3/C, 4/D, 5/E}% This needs to match \NumOfColumns 

\tikzset{Square/.style={
    inner sep=0pt,
    text width=\Size, 
    minimum size=\Size,
    draw=black,
    fill=yellow!20,
    align=center
    }
}

% Define the contents of the cells here.
\newcommand{\NodeAA}{Node $(1,1)$}%
\newcommand{\NodeAB}{Node $(1,2)$}%
\newcommand{\NodeAC}{Node $(1,3)$}%
\newcommand{\NodeAD}{Node $(1,4)$}%
\newcommand{\NodeAE}{Node $(1,5)$}%

\newcommand{\NodeBA}{Node $(2,1)$}%
\newcommand{\NodeBB}{Node $(2,2)$}%
\newcommand{\NodeBC}{Node $(2,3)$}%
\newcommand{\NodeBD}{Node $(2,4)$}%
\newcommand{\NodeBE}{Node $(2,5)$}%

\newcommand{\NodeCA}{Node $(3,1)$}%
\newcommand{\NodeCB}{Node $(3,2)$}%
\newcommand{\NodeCC}{Node $(3,3)$}%
\newcommand{\NodeCD}{Node $(3,4)$}%
\newcommand{\NodeCE}{Node $(3,5)$}%

\newcommand{\NodeDA}{Node $(4,1)$}%
\newcommand{\NodeDB}{Node $(5,2)$}%
\newcommand{\NodeDC}{Node $(5,3)$}%
\newcommand{\NodeDD}{Node $(5,4)$}%
\newcommand{\NodeDE}{Node $(5,5)$}%

\newcommand{\NodeEA}{Node $(5,1)$}%
\newcommand{\NodeEB}{Node $(5,2)$}%
\newcommand{\NodeEC}{Node $(5,3)$}%
\newcommand{\NodeED}{Node $(5,4)$}%
\newcommand{\NodeEE}{Node $(5,5)$}%

\begin{document}
\begin{tikzpicture}[draw=black, ultra thick, x=\Size,y=\Size]
    \foreach \col/\colLetter in \Sequence {%
        \foreach \row/\rowLetter in \Sequence{%
            \pgfmathtruncatemacro{\value}{\col+\NumOfColumns*(\row-1)}
            \def\NodeText{\expandafter\csname Node\rowLetter\colLetter\endcsname}
            \node [Square] at ($(\col,-\row)-(0.5,0.5)$) {\NodeText};

This looks great. I'm generating a lot of different sets of "node" values, so my use is a little different, but it certainly does what I wanted! I'm surprised the better answer (so far) wasn't just some fancy tabular environment. –  Jefromi Mar 28 '12 at 3:59
    
@Jefromi: Well that's a reason why one should always compose a fully compilable MWE, at least up to what you have so far so that the solution you get actually works for you. Updated version randomly generates the nodes based on the algorithm described. –  Peter Grill Mar 28 '12 at 4:23
    
No, I mean this does work for me - I like getting minimal working examples as answers. I'm perfectly happy having the generation outside of TeX, and that's not at all part of the question, because I'm doing some smart things that I'd rather do with a full programming language. –  Jefromi Mar 28 '12 at 4:42

The following very nice article by Will Robertson published in the PracTeX Journal describes how to make a square cells environment using basic array techniques. I haven't included any specific code for entering the cells; depending on how the cells are generated I might be inclined to use the datatool package and read in the boards from a CSV file. This would be simple to adapt to this table style.

Square cells: an array cooking lesson

Here's an example:

% This code written by Will Robertson and published in PracTeX Journal 2005-2
% "Square cells: an array cooking lesson"
% Modified for line wrapping

\documentclass{article}
\usepackage{array}
\usepackage{calc}

\newlength\celldim
\newlength\fontheight
\newlength\extraheight
\newcounter{sqcolumns}

\newcolumntype{S}{
 @{}
 >{\centering \rule[-0.5\extraheight]{0pt}{\fontheight + \extraheight}%
 \begin{minipage}{\celldim}\centering}
 p{\celldim}
 <{\end{minipage}} 
 @{} }

\newcolumntype{Z}{ @{} >{\centering} p{\celldim} @{} }

\newenvironment{squarecells}[1]
  {\setlength\celldim{4.5em}%
   \settoheight\fontheight{A}%
   \setlength\extraheight{\celldim - \fontheight}%
   \setcounter{sqcolumns}{#1 - 1}%
   \begin{tabular}{|S|*{\value{sqcolumns}}{Z|}}\hline}
% squarecells tabular goes here
  {\end{tabular}}

\newcommand\nl{\tabularnewline\hline}

\begin{document}
  \Huge
  \begin{squarecells}{4}
    This is a long line & 3  & 2  & 13 \nl
    5  & 10 & 11 & 8  \nl
    9  & 6  & 7  & 12 \nl
    4  & 15 & 14 & 1  \nl
  \end{squarecells}
\end{document}

This seems to sometimes do some weird things when the text in the cells wraps - the first line centered and second line going to the bottom of the cell. –  Jefromi Mar 28 '12 at 3:42
    
@Jefromi I've updated the answer to solve the wrapping problem. Thanks for pointing it out. –  Alan Munn Mar 28 '12 at 4:10

This looks like a nice package. Unfortunately at least on TL there's no documentation to be found for it. –  Alan Munn Mar 28 '12 at 12:54
    
documentation is on CTAN: mirror.ctan.org/macros/latex/contrib/easy/doc/doctable.pdf –  Herbert Mar 28 '12 at 15:53
    
Thanks, this is the kind of thing I figured must exist somewhere. –  Jefromi Mar 28 '12 at 19:13
    
Simple and elegant! –  Nik Oct 31 '13 at 21:21

Using the tabstackengine package introduced at Writing a table with equally spaced columns, based on the widest column, we have the following MWE. You can control the size of the box and rule thicknesses with the definitions of \fboxsep, \fboxrule, \mystrutwidth, and \mystrutdepth.

\documentclass{article}
\usepackage{tabstackengine}
\usepackage{fixltx2e}
% YOU CONTROL THE NEXT FOUR LINES
\fboxsep=3pt
\fboxrule=.8pt
\def\mystrutwidth{2.5\baselineskip}
\def\mystrutdepth{1\baselineskip}
%
\def\mystrut{\rule[-\mystrutdepth]{0ex}{\mystrutwidth}}
\newcommand\bngo[1]{\kern-\fboxrule\fbox{\mystrut\makebox[\mystrutwidth]{#1}}}%
\setstackgap{L}{\mystrutwidth+2\fboxsep+\fboxrule}
\begin{document}
\tabbedLongstack{
\bngo{8} & \bngo{29} & \bngo{45} & \bngo{54} & \bngo{68}\\
\bngo{9} & \bngo{19} & \bngo{40} & \bngo{49} & \bngo{67}\\
\bngo{15} & \bngo{24} & \stackanchor{Free}{Space} & \bngo{46} & \bngo{71}\\
\bngo{7} & \bngo{26} & \bngo{32} & \bngo{60} & \bngo{64}\\
\bngo{14} & \bngo{28} & \bngo{37} & \bngo{46} & \bngo{66}
}
\end{document}
