I searched for a long time to find a solution to let a caption of a figure and/or a table expand into the outside margin. I'm able to get a figure/table where the width is textwidth
plus marginparwidth
. See my MWE down below using a solution on stackexchange.
EDIT: Thanks to Steven B. Segletes, who found the right question, I was able to fix this with the command \captionsetup{margin={0pt,-\marginparwidth}}
using the caption
-package. I edited the code below, too.
\documentclass[%
12pt,
BCOR=15mm,
captions=tableheading,
DIV=current,
]{scrbook}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}
\usepackage[demo]{graphicx}
\usepackage[
top=30mm,
bottom=40mm,
inner=30mm,
outer=55mm,
marginparsep=5mm,
marginparwidth=30mm,
]{geometry}
\usepackage[leqno, fleqn]{amsmath}
\usepackage{amsfonts}
\usepackage{amssymb}
\usepackage{booktabs}
\usepackage{array, tabularx}
\usepackage{ifoddpage}
\newlength\fullwidth\fullwidth=\textwidth \advance\fullwidth by \marginparwidth
\begin{document}
\begin{figure}
\checkoddpage
\edef\side{\ifoddpage l\else r\fi}
\makebox[\textwidth][\side]{%
\includegraphics[width=\fullwidth]{figure}
}%
\captionsetup{margin={0pt,-\marginparwidth}}
\caption{Long captiontext do get two lines, so I can see, if the caption expands into the margin.\label{fig:label}}
\end{figure}
\begin{table}[h]
\captionsetup{margin={0pt,-\marginparwidth}}
\caption{Instabile Isotope können unter Aussendung von Kernteilchen zerfallen. Dabei bilden sie neue Isotope.\label{tab:radiozerfall}}
\checkoddpage
\edef\side{\ifoddpage l\else r\fi}
\makebox[\textwidth][\side]{%
\begin{tabularx}{1.01\fullwidth}{>{\kern-\tabcolsep}XXXXXX<{\kern-\tabcolsep}}
\toprule
Produkt & \multicolumn{2}{c}{Strahlungs-} & \multicolumn{3}{c}{Eigenschaften der Strahlungsteilchen} \\
& teilchen & bezeichnung & Kernladungs\-zahl & Nukleonen\-zahl & Durchdrin\-gung \\
$^{A-4}_{Z-2}\text{E}$ & He-Kern & $\alpha$-Strahlung & $+2$ & 4 & gering \\
$^{A}_{Z+1}\text{E}$ & Elektron & $\beta$-Strahlung & $-1$ & 0 & mittel \\
unverändert & Photon & $\gamma$-Strahlung & $\phantom{-}0$ & 0 & groß \\ \bottomrule
\end{tabularx}}
\end{table}
\end{document}
Thanks in advance.

Here's an options using the
caption
package and itsmargin
key (I added theshowframe
option togeometry
so as to have a visual help for the page layout; I also added\marginparsep
to the width of the figure, table and captions, but this is optional):The result:
