I have a tabular
containing several chemical formulas and unfortunately, even though the text is spaced correctly the molecules touch the border like this:
Code :
\subsubsection{Groupes}
\begin{tabular}{|c|c|c|}
\hline
Acides carboxyliques & \scalebox{.7}{\chemfig{R-C([1]=O)-[7]O-[8]H}} & - oique\\
\hline
Ester & \scalebox{.7}{\chemfig{R-C([1]=O)-[7]R'}} & R -oate de R' -yle
\end{tabular}
How can I fix that?
