# Roman numeral numbering for introductions

Is there a way to automatically use roman numeral numbering for introduction pages and introductory tables, which would then switch to arabic numerals for the rest of the document?

-

If you are using the book class, start your document with \frontmatter. This changes the numbering to roman numerals. Then mark the main part of with \mainmatter. There are also \appendix (which changes the chapter numbering to uppercase letters) and \backmatter.

This will also work with scrbook. –  Gonzalo Medina Aug 16 '11 at 0:01

If you are using an article you can use:

\pagenumbering{Roman}
\pagenumbering{arabic}

-

\frontmatter and \mainmatter will suffice for different styles of page numbering, but not for roman numbering of introductory tables (which are quite uncommon). Assuming you have only one frontmatter chapter that includes tables, the following should do the trick:

\documentclass{book}

\begin{document}

\frontmatter

\begingroup
\renewcommand{\thetable}{\Roman{table}}

\chapter{foo}

Some text.

\begin{table}
\caption{bla}
\end{table}

\endgroup

\mainmatter

\chapter{bar}

Some text.

\begin{table}
\caption{blubb}
\end{table}

\end{document}


For report and similar classes, replace \frontmatter with \pagenumbering{Roman} and \mainmatter with \cleardoublepage\pagenumbering{arabic}.

While using groups like this is probably fine, I'd be a little wary of doing this in general. Some packages might assume that the main document text isn't at different scoping levels (e.g., with home-grown counters, or document-spanning variables). –  Will Robertson Oct 26 '10 at 14:57
