Bildunterschriften unter Abbildungen zentrieren

Question

Gibt es eine Möglichkeit, dies zu tun? Alle meine sind linksbündig ausgerichtet, ich möchte sie jedoch zentriert haben. Wie wird das gemacht?

Ebenfalls damit verbunden: Wie kann ich alle meine Bildunterschriften fett darstellen?

\documentclass[a4paper,12pt,fleqn,titlepage]{report}
\usepackage[margin=2.0cm]{geometry}                % See geometry.pdf to learn the layout options. There are lots.
\geometry{letterpaper}                   % ... or a4paper or a5paper or ... 
%\geometry{landscape}                % Activate for for rotated page geometry
\usepackage[parfill]{parskip}    % Activate to begin paragraphs with an empty line rather than an indent

\begin{document}

\begin{table}[h!]
\centering
\captionsetup{width=13cm}
\caption{Load of stuff above the table which is wider than the table, can use width to limit that as above but want it centralised, also might be numbers in here which means when I want to embolden the entire caption from the preamle so that it does it for all figures in my document that the numbers like this $n=1,2,3,4,5,6$ and $7$ will embolden too. If I put this in at the moment it looks like my actual text and so there is lttle way to discern between the two.}
\vspace{0.3cm}
\begin{tabular}{| l | l | l |}
\hline
Thing1 & Thing2 & Thing3 \\ \hline
blah1 & blah2 & blah3 \\ \hline
\end{tabular}

\end{table}

\end{document}

Bitte entschuldigen Sie die Einleitung, da ich nicht wirklich weiß, was sich auf was bezieht. Ich weiß nur, dass diese im Laufe der Zeit gesammelt wurden, um mein gesamtes Dokument schreiben zu können, sodass alle irgendwann verwendet werden. Wenn Sie möchten, kann ich sie herausnehmen ...

Ich möchte also eine Möglichkeit, die Schriftgröße aller meiner Bildunterschriften global fett zu markieren, zu zentralisieren und zu ändern. Mit zentralisieren meine ich eine zentrierte Ausrichtung, sodass sie nicht linksbündig ausgerichtet sind.

Answer 1

Sie brauchen kein zusätzliches Paket. Da Sie laden caption, können Sie dessen Funktionen nutzen:

\documentclass[a4paper,12pt,fleqn,titlepage]{report}
\usepackage{caption}

\captionsetup{width=.75\textwidth,font={bf,scriptsize},skip=0.3cm,within=none}


\begin{document}

\chapter{Test}
\begin{table}
\centering
\caption{Load of stuff above the table which is wider than the table, can use width to limit that as above but want it centralised, also might be numbers in here which means when I want to embolden the entire caption from the preamle so that it does it for all figures in my document that the numbers like this $n=1,2,3,4,5,6$ and $7$ will embolden too. If I put this in at the moment it looks like my actual text and so there is lttle way to discern between the two.}
\begin{tabular}{| l | l | l |}
\hline
Thing1 & Thing2 & Thing3 \\ \hline
blah1 & blah2 & blah3 \\ \hline
\end{tabular}
\label{table:stuff}
\end{table}

\end{document}

Answer 2

Kommt das dem näher, was Sie suchen? Die erste Tabelle ist das, was Sie hatten. Die zweite verwendet boxhandler. Die Überschriftenbreite, die Schriftgröße der Überschrift und die Fettschrift des normalen Textes in der Überschrift wurden alle in der Präambel geändert und gelten für alle Tabellen und Abbildungen. Die fettgedruckte Mathematik in der Überschrift kann nicht global in den Tabellenüberschriften geändert werden, ohne sie auch im Rest Ihres Dokuments zu ändern. Daher \mathbfist dies Teil jeder Abbildungsüberschrift, die Mathematik verwendet. Die Parameter, die ich verwendet habe, sind Überschriftenbreite= .5\textwidthund die Überschrift ist in Skriptgröße fett.

Verwenden\makebox[\textwidth]{}

\makebox[\textwidth]{
\captionsetup{width=13cm}
