Stata's not strong on metaphysics, in this 
case on tabulating data you don't have but 
might have had. The work-arounds appear 
to be user-written. 

One discussion of your problem was in 

Problems with tables, Part II. 
Stata Journal 3(4):420--439 (2003) 

which reviewed two user-written commands, -tabcount- 
and -groups-, aimed at this and related issues. 

Both can be downloaded from SSC. 

In your specific case, it is difficult to 
see how you could get a row for "large" unless
that was a defined value label for a numeric
value not present in the data.
