Align Decimals in table with additional integer and parenthesis

Question

I am creating a table and am aligning the numbers in the column with the package \dcolumn. In "normal" cases this works, but not if I add parenthesis.

This is a minmal example that shows my problem:

\documentclass[a4paper,12pt,numbers=noenddot,fleqn]{scrreprt}
\usepackage{dcolumn}
\begin{document}

\begin{table}[htb]
\centering
\begin{tabular}{lD{.}{.}{3}l}

0   & 100(1) &  0.80(6) \\
1   & 71.9(8)&  0.797(6)\\
2   & 7.8(6) &  0.788(6)\\

\end{tabular}
\end{table}
\end{document}

Is there a way I can align the integer in the middle row aswell?

Some things I tried:

• Chancing the "3" in the line with \begin{tabular} to different integers
• using \rlap()
• following some incomplete instructions given here: RevTeX-4.2 and dcolumn : align decimal with integer numbers

...but obviously nothing worked... Thank you!

Answer 1

With siunitx instead of dcolumn:

\documentclass[a4paper,12pt,numbers=noenddot,fleqn]{scrreprt}
\usepackage{siunitx}
\begin{document}

\begin{table}[htb]
\centering
\begin{tabular}{lS[table-format=3.1(1)]S[table-format=1.3(1)]}
0   & 100(1) &  0.80(6) \\
1   & 71.9(8)&  0.797(6)\\
2   & 7.8(6) &  0.788(6)\\
\end{tabular}
\end{table}
\end{document}
