I'm using the {threeparttable} package because I want to use table notes, but I'm having a problem resizing my tables. If I use {adjustbox} to enclose {tabular} (or {tabularx}), I get an error message:

! You can't use `\hrule' here except with leaders. \caption@hrule
->\hrule 
                    \@height \z@  l.23 \end{tabular}}

The same applies if I use \resizebox or \scalebox at the same point in the code.

If I use {adjustbox} and enclose {threeparttable}, the code runs, but the fontsize of the caption and table note are also scaled down...

... which is not what I want!

Does anyone know a way to resize the table font only when using package {threeparttable}?

\documentclass[a4paper,14pt]{scrreprt}

\usepackage{graphicx}
\usepackage{adjustbox}
\usepackage{threeparttable}
\usepackage[labelfont=bf]{caption}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage[a4paper, bindingoffset=0.5cm, tmargin=2.4cm, bmargin=3.4cm, lmargin=3.5cm, rmargin=2.5cm, footskip=2.4cm]{geometry}

threeparttable wants to see tabular and tablenotes at the outer level, not buried into adjustbox.

Thinks very carefully before deciding to scale a table. For instance, a body text of 14pt is humongous and will make the scaled table disappear with respect to the text.

I reduced to 11pt, which is a quite large font size.

\documentclass[a4paper,11pt]{scrreprt}

\usepackage{graphicx}
\usepackage{adjustbox}
\usepackage{threeparttable}
\usepackage[labelfont=bf]{caption}
\usepackage{booktabs}
\usepackage{siunitx}
\usepackage[a4paper, bindingoffset=0.5cm, tmargin=2.4cm, bmargin=3.4cm, lmargin=3.5cm, rmargin=2.5cm, footskip=2.4cm]{geometry}

\begin{document}
This is some text which refers to Table~\ref{tab:Table}
\begin{table}
\centering
\caption{Table caption.}
\label{tab:Table}
\begin{adjustbox}{max width=\textwidth}
\begin{threeparttable}
\begin{tabular}{@{}l*{10}{c}@{}}
\toprule
Item & Col 2 & Col 3 & Col 4 & Col 5 & Col 6 & Col 7 & Col 8 & Col 9 & Col 10 & Col 11 \\
\midrule
Some sort of stuff\tnote{a} & 107.5 & 5.62 & 89.1 & \num{14367.7} & 3.4 & 21.9 & 112.6 & \num{18644} & 432.4 & 17 \\
\bottomrule
\end{tabular}
\begin{tablenotes}
\small
\item[a] This sort of stuff is only available in winter.
\end{tablenotes}
\end{threeparttable}
\end{adjustbox}
\end{table}
Some more text.

Would I scale also the caption? No way.

  • Many thanks @egreg. Like a lot of things, it seems easy when you know how! I'm not really using a 14-point font, I just used it in the example to make the scaling more obvious, and to make it clear that the caption font was being downsized too.

  • PS What's the alternative to scaling if one has a lot of columns, is it just a question of adjusting the table font size manually?
