Hello,
I am making progress and I almost get what I want to achieve but I still
have two problems :
how to color cells not containing numbers with the same color as the others
?
how to color in salmon, for example, cells 1 2 ?
3
Thank you
Fabrice

I also wonder where is the boundary of ConTeXt. The boundaries are set and shift by users (the mailing list) and curiosity (personal).
