I have a number with an exponent and an uncertainty that I want to display in an S-column in a table. When I just put it in, the spacing is terrible, and if I tell the column how much space to reserve for the number, the brackets around the value and the uncertainty disappear, making the expression faulty.
It looks something like this:
\documentclass{article}
\usepackage[separate-uncertainty]{siunitx}
\begin{document}
\begin{tabular}{| S | S[table-format=1.2(2)e-1] |}
{not reserved} & {reserved} \\
1,72(53)e-3 & 1,72(53)e-3 \\
\end{tabular}
\end{document}

How can I aovoid this but still have a nicely spaced table?
