It seems that all captions in Tufte-book are placed in the margin.
I have a full-width table where I can place the caption above the table using
\begin{table*}[b]
but how do I specify the caption to have the same width as the table?
Complete MWE:
\documentclass[b5paper,11pt,nobib,symmetric,justified,notoc]{tufte-book}
\begin{document}
\begin{table*}[b]
\caption{Foo-bar Foo-bar Foo-bar Foo-bar Foo-bar Foo-bar}
\begin{tabular}{llllllllll}
Foo & bar & Foo & bar & Foo & bar & Foo & bar & Foo & bar
\end{tabular}
\end{table*}
\end{document}
