Resizing table from external latex file

Question

So I am aware that this question has been asked and answered a few times, however I cannot get the existing solutions to work for me.

I have a latex table that is the output from Stata (statistical software) and I am loading it into my existing latex document using the \input{} command. The table is too big, and I need to scale it down.

My table file looks like this:

\begin{table}[htbp]\centering
\def\sym#1{\ifmmode^{#1}\else\(^{#1}\)\fi}
\caption{Linear Model, h=10}
\begin{tabular}{l*{5}{c}}
\hline\hline
                    &\multicolumn{1}{c}{(1)}&\multicolumn{1}{c}{(2)}&\multicolumn{1}{c}{(3)}&\multicolumn{1}{c}{(4)}&\multicolumn{1}{c}{(5)}\\
                &\multicolumn{1}{c}{Corrupt Items}&\multicolumn{1}{c}{Corrupt Resources}&\multicolumn{1}{c}{Diversion Items}&\multicolumn{1}{c}{Fraud Items}&\multicolumn{1}{c}{Overinvoiced Items}\\
\hline

T                   &     -0.0226         &     -0.0194         &     -0.0389         &   0.0000768         &     -0.0226         \\
                &     (-0.99)         &     (-0.45)         &     (-1.31)         &      (0.00)         &     (-0.99)         \\

\hline\hline
\multicolumn{6}{l}{\footnotesize All are tobit regressions, censored at 0}\\
\multicolumn{6}{l}{\footnotesize \sym{*} \(p<0.05\), \sym{**} \(p<0.01\), \sym{***} \(p<0.001\)}\\
\end{tabular}
\end{table}

And then as suggested by this page I attempt to call it and rescale it in this manner:

\documentclass{beamer}
\mode<presentation> {
\usetheme{Madrid}
}
\usepackage{graphicx} 
\usepackage{booktabs} 
\usepackage{graphics}
\usepackage{subcaption}
\usepackage{mwe}

\newlength{\tempwidth}

\begin{document}

\begin{frame}
\begin{table}
\let\center\empty
\let\endcenter\relax
\centering
\resizebox{.5\width}{!}{\input{tablefile.tex}}
\end{table}
\end{frame}

\end{document}

Yet, it is still throwing me errors, saying "Not in outer par mode". What is going on here?

Answer 1

Your suggested code had table inside table and table inside resizebox, neither of which will work.

If you just input the table

\documentclass{beamer}
\mode<presentation> {
\usetheme{Madrid}
}
\usepackage{graphicx} 
\usepackage{booktabs} 
\usepackage{graphics}
\usepackage{subcaption}
\usepackage{mwe}

\newlength{\tempwidth}

\begin{document}

\begin{frame}
{\input{tablefile.tex}}


\end{frame}

\end{document}

then it is a bit too wide

Overfull \hbox (18.97734pt too wide) in paragraph at lines 4--17

If you want to shrink it without editing the generated file in any way probably the best hook is \centering. \small was enough for the original example, for the larger table in the edited example, you need \tiny, although I pity your audience if they try to read this much data on a slide:-)

\documentclass{beamer}
\mode<presentation> {
\usetheme{Madrid}
}
\usepackage{graphicx} 
\usepackage{booktabs} 
\usepackage{graphics}
\usepackage{subcaption}
\usepackage{mwe}

\newlength{\tempwidth}

\begin{document}

\begin{frame}
{
\let\oldcentering\centering
\renewcommand\centering{\tiny\oldcentering}
\input{tablefile.tex}}


\end{frame}

\end{document}

Answer 2

Instead of resizing the table yourself, you could tell beamer to shrink the whole frame. For example \begin{frame}[shrink=30] should be enough to accommodate your table.

\documentclass{beamer}
\mode<presentation> {
\usetheme{Madrid}
}
%\usepackage{graphicx} 
\usepackage{booktabs} 
%\usepackage{graphics}
\usepackage{subcaption}
%\usepackage{mwe}

\newlength{\tempwidth}

\def\sym#1{\ifmmode^{#1}\else\(^{#1}\)\fi}

\begin{document}

\begin{frame}[shrink=30]
\begin{table}
\caption{Linear Model, h=10}
\begin{tabular}{l*{5}{c}}
    \toprule
    & \multicolumn{1}{c}{(1)} & \multicolumn{1}{c}{(2)} & \multicolumn{1}{c}{(3)} & \multicolumn{1}{c}{(4)} & \multicolumn{1}{c}{(5)}\\
    & \multicolumn{1}{c}{Corrupt Items} & \multicolumn{1}{c}{Corrupt Resources} & \multicolumn{1}{c}{Diversion Items} & \multicolumn{1}{c}{Fraud Items} & \multicolumn{1}{c}{Overinvoiced Items}\\
    \midrule
    model & & & & & \\
    T & -0.0226 & -0.0194 & -0.0389 & 0.0000768 & -0.0226 \\
    & (-0.99) & (-0.45) & (-1.31) & (0.00) & (-0.99) \\[1em]
    R & 0.00247 & 0.00510 & 0.00379 & -0.00140 & 0.00247 \\
    & (0.78) & (0.86) & (0.94) & (-0.54) & (0.78) \\[1em]
    R*T & -0.00539 & -0.0161\sym{*} & -0.00301 & -0.00108 & -0.00539 \\
    & (-1.35) & (-2.13) & (-0.58) & (-0.32) & (-1.35) \\[1em]
    Constant & 0.0766\sym{***} & 0.105\sym{**} & 0.0381 & 0.0163 & 0.0766\sym{***}\\
    & (4.45) & (3.26) & (1.71) & (1.14) & (4.45) \\
    \midrule
    sigma & & & & & \\
    Constant & 0.0441\sym{***} & 0.0827\sym{***} & 0.0531\sym{***} & 0.0352\sym{***} & 0.0441\sym{***}\\
    & (9.41) & (9.17) & (6.97) & (6.93) & (9.41) \\
    \midrule
    Observations&54 &54 &54 &54 &54 \\
    \bottomrule
    \multicolumn{6}{l}{\footnotesize All are tobit regressions, censored at 0}\\
    \multicolumn{6}{l}{\footnotesize \sym{*} \(p<0.05\), \sym{**} \(p<0.01\), \sym{***} \(p<0.001\)}\\
\end{tabular}
\end{table}
\end{frame}

\end{document}

Answer 3

If the table were in fact too wide, one could rescale it using the following kludge. The \begroup ... \egroup makes the changes local (especially \endtable). The minipage is needed for \caption, but you need to know the width of the tabular if you want the caption centered.

\documentclass[12pt, a4paper]{scrartcl}

\usepackage{graphicx}

\newlength{\tempwidth}

\begin{document}

\begin{table}
\bgroup
  \def\table[#1]{}% gobble [htbp]
  \let\endtable\relax
  \let\centering\relax
  \settowidth{\tempwidth}{\def\caption#1{}% width of tabular
    \input{tablefile.tex}}%
  \resizebox{\textwidth}{!}{\begin{minipage}{\tempwidth}%
    \input{tablefile.tex}
  \end{minipage}}%
\egroup
\end{table}

\end{document}

Here is a beamer version. The problem occurs when beamer tries to gather the contents of the frame environment into a macro (\test). The environ package had the same problem gathering it into \BODY. One can fix it by putting the contents of the frameinto a savebox outside the frame environment.

Note that with beamer, captions are not self centering.

\documentclass{beamer}
\mode<presentation> {
\usetheme{Madrid}
}
%\usepackage{graphicx} 
\usepackage{booktabs} 
%\usepackage{graphics}
\usepackage{subcaption}
%\usepackage{mwe}

\newlength{\tempwidth}
\newsavebox{\tempbox}

\begin{document}

\savebox{\tempbox}{%
  \expandafter\edef\csname @captype\endcsname{table}% table caption
  \def\table[#1]{}% gobble [htbp]
  \let\endtable\relax
  %\let\centering\relax
  \settowidth{\tempwidth}{\def\caption#1{}% gobble caption
    \input{tablefile}}% width of tabular
  \resizebox{\textwidth}{!}{\begin{minipage}{\tempwidth}%
    \input{tablefile}
  \end{minipage}}%
}

\begin{frame}
\frametitle{Test}
\usebox{\tempbox}
\end{frame}
\end{document}
