% V1.02 : 12/05/2012 -> Modification de la macro \tableur : on peut désormais écrire \tableur{A,B,C,D} ou \tableur{A-D}
% V1.03 : 13/05/2012 -> Modification de la macro \celtxt : on peut désormais insérer l'accent circonflexe dans du texte et si le texte est plus large que la cellule, le trait gris de séparation des cellules n'est plus visible (le texte s'écrit par dessus).
% V1.04 : 13/05/2012 -> Alélioration de la macro \celtxt : le texte est réduit pour ne pas effacer les traits de cellule
