[NTG-context] dashed or dotted lines in tables

[Ricard Roca]

Yes, more or less.

I meant drawing the normal horizontal and vertical rules that separate 
rows and columns dashed or dotted instead of continuous, but using TeX 
itself, i.e. with an option or command from one of the table packages, 
redefining some internal macro, etc. But I see that's not (easily) 
doable, and one has to use Metapost.

Thanks
