First of all, my sincere thanks to John, Tony, Geoff, Ned, David, Craig,
and Monique for taking the time to tackle this question.

I myself had previously set up an Excel spreadsheet using the
IF(COUNTIF) function -- for example, <=IF(COUNTIF('Employee
columns'!C$2:C$35,Procedures!$A2)=0,"",D$1)>, with a second function for
sorting the results -- but this is beside the point. I'm not asking how
to create the grid; I'm asking, why do we even need to create it?

My original description was (IMNSHO) an excellent user interface for a
many-to-many relationship between two entities. There ought to be an app
that already offers this as a native function, and I think it's a shame
if there isn't.
