'mmm,

Nice question.

I'd say that was when we went from ipfw to ipfw2...
And ipfw has now become ipfw again.

Tables are at least supported in all versions that are not EoL, and the 
full range of 8.x

This is from soem systems I have about:
7.3-STABLE FreeBSD 7.3-STABLE #0: Wed Jun 30 22:15:57 CEST 2010
AND
6.4-PRERELEASE FreeBSD 6.4-PRERELEASE #85: Wed Nov 12 12:46:53 CET 2008

      ipfw table number add addr[/masklen] [value]
      ipfw table number delete addr[/masklen]
      ipfw table {number | all} flush
      ipfw table {number | all} list

So I'd expect just about everybody with IPFW to have tables.
And if not, then their version is so old that they better know what they 
are doing. Because maintaining these systems needs a lot of expertise to 
fix security bugs....

hope that helps,
