My question closely relates to this: Making table width fit into text width.

The answer's code is:

\maketitle \begin{table}[hbtp] \footnotesize \centering \begin{tabulary}{1.0\textwidth}{C||L|L|L|L} \hline & Function & Pre conditions & Post conditions & Constraints \\ \hline\hline R1 & An election official is assigned for each precinct & Precincts and elections officials are created & Unique one on one mapping from an election official to precinct & Before voting starts\\ \hline \end{tabulary} \caption{Requirements before voting starts} \label{eoRequirements} \end{table}

What I would like to do is specify the width of one of the columns using, for example:

\maketitle \begin{table}[hbtp] \footnotesize \centering \begin{tabulary}{1.0\textwidth}{C||L|L|L|p{10em}} \hline & Function & Pre conditions & Post conditions & Constraints \\ \hline\hline R1 & An election official is assigned for each precinct & Precincts and elections officials are created & Unique one on one mapping from an election official to precinct & Before voting starts\\ \hline \end{tabulary} \caption{Requirements before voting starts} \label{eoRequirements} \end{table}

This seems to make the total table width larger than \textwidth. How can I get the table width to remain at \textwidth while also specifying 1 or more column widths with p{.}? Thanks so much for any replies.

a p column is more or less just a column with a \parbox and fortunately \parbox works as expected. (The behaviour of the p columns seems slightly unexpected)

enter image description here

\documentclass{article} \usepackage{tabulary} \setlength\extrarowheight{2pt} \begin{document} \begin{table}[hbtp] \footnotesize \centering \begin{tabulary}{1.0\textwidth}{C||L|L|L|l} \hline & Function & Pre conditions & Post conditions & \parbox{10em}{Constraints}\\ \hline\hline R1 & An election official is assigned for each precinct &Precincts and elections officials are created & Unique one on one mapping from an election official to precinct & \parbox{10em}{Before voting starts}\\ \hline \end{tabulary} \caption{Requirements before voting starts} \label{eoRequirements} \end{table} \noindent X\dotfill X \end{document}

To use p columns I think the required fix is as below:

\documentclass{article} \usepackage[debugshow]{tabulary} \setlength\extrarowheight{2pt} \makeatletter \def\z#14#2!!{\def\TY@classz{#17#2}} \expandafter\z\TY@classz!! \makeatother \begin{document} \begin{table}[hbtp] \footnotesize \centering \begin{tabulary}{1.0\textwidth}{C||L|L|L|p{10em}} \hline & Function & Pre conditions & Post conditions & Constraints\\ \hline\hline R1 & An election official is assigned for each precinct &Precincts and elections officials are created & Unique one on one mapping from an election official to precinct & Before voting starts\\ \hline \end{tabulary} \caption{Requirements before voting starts} \label{eoRequirements} \end{table} \noindent X\dotfill X \end{document}

  • Thanks so much David. It's so great how nice people are on here. One thing I noticed is that the behavior doesn't quite work right if I specify tymin too large: \setlength{\tymin}{0.25\textwidth} seems to mess your solution up. Commented Oct 31, 2014 at 6:00

    @kennyB hmm will look later,but tymin=.25\textwidth isn't achievable so best you could hope for there would be some kind of warning. you have 4 LCR columns and if they are all at least .25\textwidth they will total at least \textwidth, then you have 10em from the p column the width of 5 rules, one rule sep and 10 tabcolsep cell padding, all specified to total \textwidth, which can't work.....
