# Multiline Caption

I want a caption of two lines, with the second line not centered but aligned to the left.

This is the result of the following code, \captionsetup{justification=raggedright} doesn't seem to work. What am I doing wrong?

\documentclass[a4paper,twoside,12pt]{scrreprt}
\usepackage{fontspec}
\usepackage{caption}
\usepackage{booktabs}
\begin{document}
\begin{table}
\centering
\captionsetup{justification=raggedright}
\begin{tabular}{cc}
\toprule
A & B
\\ \midrule
11111111111111111  & 1111111111111111\\
22222222222222222  & 2222222222222222\\
33333333333333333  & 3333333333333333\\
44444444444444444  & 4444444444444444\\
55555555555555555  & 5555555555555555\\
66666666666666666  & 6666666666666666\\
\bottomrule
\end{tabular}
\caption{Caption caption caption caption\\
caption caption}
\end{table}
\end{document}

• Did you try \captionsetup{width=0.5\linewidth,justification=raggedright} – Jesse Jun 20 '14 at 10:18
• Would this help? tex.stackexchange.com/q/128485/34618 – Jesse Jun 20 '14 at 10:19
• Interestingly it also seems to depend on the length of the caption. If I add two extra caption after the \ then it is left aligned, but only one, and the last line is centered. – daleif Jun 20 '14 at 13:21
• The trick from this question tex.stackexchange.com/questions/120411/…, seems to help. No idea though why this check interfere – daleif Jun 20 '14 at 13:24
• or you could just use a \parbox inside the caption. – John Kormylo Jun 23 '14 at 14:28

If you use a threeparttable environment, it computes the width of your table, and it works either with the plain or the hang formats:

 \documentclass[a4paper,twoside,12pt]{scrreprt}
\usepackage[utf8]{inputenc}
\usepackage{fourier, heuristica}
\usepackage{caption}
\usepackage{booktabs}
\usepackage{threeparttablex}

\begin{document}

\begin{table}[!h]
\captionsetup{format =plain}%

\begin{threeparttable}
\begin{tabular}{cc}

\caption{Caption caption caption caption\\

\end{threeparttable}
\end{table}

Note that it doesn't seem to work with the ThreePartTableenvironment (from threeparttablex), so that you can't break your tables through pages.

Hang is the standard caption format in KOMA-Script classes. Therefore you only have to measure the width of the float und to set \setcapwidth to the result. The caption package is not needed.

\documentclass[twoside,12pt]{scrreprt}
\usepackage{fontspec}
\usepackage{booktabs}

\newlength\floatwidth
\newcommand\MyFloat[1]{%
\settowidth\floatwidth{#1}%
\setcapwidth[c]{\floatwidth}%
#1%
}

\begin{document}
\begin{table}
\centering
\MyFloat{%
\begin{tabular}{cc}
\toprule
A & B\\
\midrule
11111111111111111  & 1111111111111111\\
22222222222222222  & 2222222222222222\\
33333333333333333  & 3333333333333333\\
44444444444444444  & 4444444444444444\\
55555555555555555  & 5555555555555555\\
66666666666666666  & 6666666666666666\\
\bottomrule
\end{tabular}%
}
\caption{Caption caption caption caption caption caption.}
\end{table}
\end{document}


Note: If there should be a manual line break inside the caption you have to use

  \caption{Caption caption caption caption \protect\\ caption caption.}


or maybe better

  \caption[Caption caption caption caption caption caption.]{%
Caption caption caption caption \\ caption caption.}
