How to make table caption left-aligned.

I tried \usepackage[singlelinecheck=off]{caption} but it did not work out. In other words it gives an error:

EDIT BY LOCKSTEP (moved from separate "answer"):

Here's a compilable example that doesn't show the problematic behaviour mentioned by you. Please use it as start-up aid to post a compilable example which does show the behaviour.

\documentclass{article}

\usepackage{floatrow}
\usepackage[singlelinecheck=off]{caption}

\begin{document}


\begin{table}
(Table content)
\caption{A table}
\end{table}

\end{document}

Best Answer

Seems like you want the captions to have the same width than the width of its figure/table. If this is the case, you can use the \ffigbox, and \ttabbox commands from the floatrow package. A little example:

\documentclass{article}
\usepackage{floatrow}
\usepackage[labelsep=space]{caption}

\DeclareFloatFont{tiny}{\tiny}
\floatsetup[table]{font=footnotesize,capposition=top}

\newcommand\Text{text text text text text text text}% just for the example

\begin{document}

\begin{figure}[!ht]
\ffigbox[\FBwidth]
{\caption{A figure with its caption having equal width to the figure width}\label{fig:test1}}
{\rule{4cm}{2cm}}
\end{figure}

\begin{table}[!ht]
\ttabbox[\FBwidth]
{\caption{A table with its caption having equal width to the table width}\label{fig:test1}}
{\begin{tabular}{p{3cm}p{3cm}}
\Text\Text & \Text\Text \\
\Text\Text & \Text\Text 
\end{tabular}
}
\end{table}

\end{document}
