Caption formatting does not work with bidi

Question

I am using the caption package to format figure and table captions. However, this breaks for longtable tables when the package bidi is loaded.

Here is a minimal example:

\documentclass{scrartcl}
\usepackage{lmodern}
\usepackage[xetex,pdfborder={0 0 0}]{hyperref}
\usepackage{graphicx}
\usepackage{longtable}
\usepackage{booktabs}
\usepackage[format=hang,labelfont=bf,font={small,rm},labelsep=quad]{caption}
\usepackage{bidi}

\title{A Test}
\author{Author}
\date{\today}

\begin{document}

\maketitle

This is a paragraph.

\begin{figure}
\centering
\includegraphics[width=\textwidth]{Image_1.jpg}
\caption{An image}
\end{figure}

\begin{table}
\centering
\caption{A simple table}
\begin{tabular}{ll}
\toprule
A cell & and another one \\
and a third & and a fourth \\
\bottomrule
\end{tabular}
\end{table}

\begin{longtable}{ll}
\caption{A long table}\\
\toprule
A cell & and another one \\
and a third & and a fourth \\
\bottomrule
\end{longtable}

\end{document}

This is the result:

The captions formatting works for regular table and figure captions, and it also works for longtable as long as the bidi package is not loaded.

Any ideas how to fix this?

Answer 1

You are using the KOMA-Script class scrartcl. So you can use its features to format the captions as desired:

\documentclass{scrartcl}
\usepackage{lmodern}
\usepackage{graphicx}
\usepackage{longtable}
\usepackage{booktabs}

\usepackage[pdfborder={0 0 0}]{hyperref}
\usepackage{bookmark}% <- added
\usepackage{bidi}

\KOMAoptions{captions=tableabove}% <- to get the correct spacing between caption and table
\addtokomafont{caption}{\normalfont\small}
\addtokomafont{captionlabel}{\bfseries}
\renewcommand*{\captionformat}{\quad}

Change the oder of packages:

\documentclass{scrartcl}
\usepackage{lmodern}
\usepackage[xetex,pdfborder={0 0 0}]{hyperref}
\usepackage{graphicx}

\usepackage{booktabs}
\usepackage[format=hang,labelfont=bf,font={small,rm},labelsep=quad]{caption}
\usepackage{longtable}
\usepackage{bidi}
