Enhancement : cell{even[4-Z]}{2-Z} = ...

[projetmbc]

It could be helpful to allow the use of cell{even[4-]}{2-} instead of cell{even[4-Z]}{2-Z}.

With the brand new \IfBlank macro, it should be easy to add. See page 8 of the 2022-07-05 version of usrguide via texdoc usrguide.

In fact you already can write even[4].

In this case, perhaps cell{even[4]}{from[2]} might be a better interface.
