You could also evaluate the conditional purely in MetaPost.  I don't
know if that would be faster, but it's a bit more readable to me.


\startuseMPgraphic{tablebackground}{i,j}
if (\MPvar{i} = 1) or (\MPvar{j} = 1):
      fill OverlayBox withcolor \MPcolor{fondpaille} ;
fi;
\stopuseMPgraphic

\defineoverlay
  [tablebackground]

[\useMPgraphic{tablebackground}{i=\currentxtablerow,j=\currentxtablecolumn}]

\setupxtable[background=tablebackground]
