Right justify roman page numbers in list of tables

Question

I have a scrartcl document with arabic and roman page numbers. The list of tables looks like this:

Arabic page numbers are right justified (relative to each other), whereas roman numbers are centered.

I would like to have all page numbers right justified, like this (the red line is just for illustration):

Although I suppose that the solution is probably related to the listof document options, I cannot find an appropriate setting. However, the problem also occurs with article instead of scrartcl, so it does not seem to be specific to KOMA script.

MWE:

\documentclass{scrartcl}
\begin{document}
\listoftables
\clearpage

\begin{table}
\caption{First main table.}
\end{table}
\clearpage

\setcounter{page}{95}
\begin{table}
\caption{Second main table.}
\end{table}
\clearpage

\pagenumbering{roman}

\setcounter{page}{1}
\begin{table}
\caption{First appendix table.}
\end{table}
\clearpage

\setcounter{page}{28}
\begin{table}
\caption{Second appendix table.}
\end{table}
\end{document}

Answer 1

A possible solution working for article and scrartcl (i.e. without using features of KOMA)

The page numbers are still right justified, but the width of the page number slot at the right margin is too small, because Roman numbers need more space to be typeset than arabic figures.

Increasing the value of \@pnumwidth will solve this problem, however, this will increase it for all .toc etc -- since Roman numbers are for all pages this should be no issue!

\documentclass{scrartcl}

\makeatletter
\renewcommand{\@pnumwidth}{40pt}% 40pt is just an example
\makeatother

\begin{document}


\listoftables
\clearpage

\begin{table}
\caption{First main table.}
\end{table}
\clearpage

\setcounter{page}{95}
\begin{table}
\caption{Second main table.}
\end{table}
\clearpage

\pagenumbering{roman}

\setcounter{page}{1}
\begin{table}
\caption{First appendix table.}
\end{table}
\clearpage

\setcounter{page}{28}
\begin{table}
\caption{Second appendix table.}
\end{table}
\end{document}
