@egreg I agree with you for the label, but I could do ` \caption{#1}#2` and give the `\label` outside or even do a unique parameter and give `\caption\label...` outside. For the footnotes is there an alternative way to write always `\begin{tablenotes}[para,flushleft]
\footnotesize`? Could I create a command to use at the end of the tabular?
