The minimal example below gives me a strange offset in numbers with exponential numbers. I think tabu and siunitx are getting in each others way. Is anyone aware of a workaround?
\documentclass[parskip=half]{scrartcl}
\usepackage{siunitx}
\usepackage{tabu,booktabs}
\begin{document}
\newcolumntype Z{X[c,m]{%
S[%
tight-spacing = true,
round-mode=places,
round-precision=2,
]
}}
\tabucolumn Z
\begin{tabu} to \linewidth {X[l,m,1.2]ZZZZZ}
\hline
Water vapour* & 18.01534 & -2.418379e+8 & 1.886964e+5 &
2.605& 572.4\\
\hline
\end{tabu}
\end{document}
