[O] Exponential numbers in latex table export

[Günter Lichtenberg]

Hi 

I have a document with many automatically generated tables that contain 
numbers in exponential Format, e.g. 2e09. When I export the tables to LaTeX 
and pdf I get something like 2 (-09) in the pdf, if there is no character 
after the number in the table

Minimal Example:
|--------------|
| 1.2e09 (abs) |
|      2.3e-09 |
|       3.4e09 |
|--------------|

exports to a latex table as

\begin{center}
\begin{tabular}{r}
\hline
1.2e09 (abs)\\
2.3\,(-09)\\
3.4\,(09)\\
\hline
\end{tabular}

Note that in the first line the number is an exponential, the following 2 are 
not. I could not find anything in the documentation. What am I missing?

orgmode version is 9.1.4, but the same happens with emacs 25.3 built-in 
version 8.3.
