[Tex/LaTex] force longtable to text width

longtablemarginstablestextwidth

Instead of specifying the width of each column in a longtable (see below), is there a way to get it to automatically adjust its size so that it matches the text width, but does not go into the margins?

\floatsetup[longtable]{LTcapwidth=\textwidth}
\scriptsize 
\begin{longtable}[c] 
{p{0.045\textwidth}p{0.045\textwidth}p{0.045\textwidth}p{0.045\textwidth}p{0.045\textwidth}p{0.05\textwidth}p{0.045\textwidth}p{0.045\textwidth}p{0.045\textwidth}p{0.045\textwidth} p{0.045\textwidth} p{0.045\textwidth} p{0.045\textwidth}} 
\caption{Insert caption here}
\hline \multicolumn{13}{c} %Removed code for 13 column multiple page table%
 \end{longtable}

This uses the same approach as Zarko and Skillmon, but uses a length register to avoid repeating the calculation 13 times.

\documentclass{article}
\usepackage{longtable}
\usepackage{showframe}

\newlength{\mycolwidth}

\begin{document}
\scriptsize 
\setlength{\mycolwidth}{\dimexpr \textwidth/13 - 2\tabcolsep}%
\begin{longtable}[c]{*{13}{p{\mycolwidth}}}
\caption{Insert caption here}
\endfirsthead
\hline 
\multicolumn{13}{c}{Removed code for 13 column multiple page table}\\
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13
\end{longtable}
\end{document}

There is an automatic gap of \tabcolsep on the edges, which can be removed thusly.

\documentclass{article}
\usepackage{longtable}
\usepackage{showframe}

\newlength{\mycolwidth}

\begin{document}
\scriptsize 
\setlength{\mycolwidth}{\dimexpr \textwidth - 24\tabcolsep}%
\divide \mycolwidth by 13

\begin{longtable}[c]{@{}*{13}{p{\mycolwidth}}@{}}
\caption{Insert caption here}
\endfirsthead
\hline 
\multicolumn{13}{c}{Removed code for 13 column multiple page table}\\
1 & 2 & 3 & 4 & 5 & 6 & 7 & 8 & 9 & 10 & 11 & 12 & 13
\end{longtable}
\end{document}

[Tex/LaTex] Make longtable automatically fit page (line width)

(Without knowing much about your cell contents), You can use ltablex package and convert your long table in to breakable tabularx. Here one can use X column type that will be evenly wider.

\documentclass[]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{pdflscape}
\usepackage{tabularx}
\usepackage{ltablex} % uncommenting this line will work
\keepXColumns

\title{MyTitle}
\author{Me}

\begin{document}

    \maketitle

    \section{First}
    %some words here

    \begin{landscape} %landscape mode
        \begin{tabularx}{1.5\textheight}{l|l|l|X|X}
            head1 & head2 & head3 & head4 & head5 \\
            \hline
            \endhead % all the rows above this will be repeated on every page

            %col5 goes out of the page (the real text is much longer)
            foo & foo & foo bar & foo bar foo bar foo bar & foo bar foo bar foo bar foo bar foo bar \\ \hline
            foo & foo bar foo & foo bar foo bar foo bar foo & foo bar & foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar \\ \hline
            foo & foo & foo bar foo bar foo bar foo & foo bar foo bar foo bar foo bar foo bar foo bar foo bar &  foo bar foo bar foo bar foo bar foo bar foo bar foo bar foo bar \\ \hline

            %some more rows here

        \end{tabularx}
    \end{landscape}
\end{document}

One way is to shift up the skip prior to the mid-height \tabucline with a \\[-1pt]. See below for 2nd approach.

    &                              & \multicolumn{1}{ |[1pt] l |     }{ } & \multicolumn{2}{  l |[1pt] }{ }   \\                       \hline

    &                              & \multicolumn{1}{ |[1pt] l |     }{ } &                                 & \\ \tabucline[1 pt]{1-5}

Alternately, if you want the thin line to bisect the thick line, then the approach: \\[-1pt] \tabucline[1 pt]{3-5}\\[-12.5pt]\hline works.
