# Shifting text out of tabular cell

Is there a simple and robust way to achieve what is illustrated by the two black arrows below, i.e., shifting the title in a right-aligned column right by a fixed amount.

\documentclass[12pt]{article}\usepackage{array}
\begin{document}

\begin{tabular}{l>{\raggedleft}p{3.5cm}@{}}
Coltitle1 & Coltitle2 \tabularnewline
AB & 5 \tabularnewline
A & 11 \tabularnewline
AC & 10 \tabularnewline
\end{tabular}

\begin{tabular}{l>{\raggedleft}p{3.5cm}@{}}
Coltitle1 & LongColtitle2 \tabularnewline
AB & 5 \tabularnewline
A & 11 \tabularnewline
AC & 10 \tabularnewline
\end{tabular}
\end{document}

I'd like to avoid bad box(es)-warnings. Also, I would prefer (=not absolutely necessary) if the right end of the table would stay where it is, i.e., directly adjacent to the numbers. I.e.,

5|                                  5  |
10|                                 10  |
...|                                  ...|

where | marks the right end of the table.
