That one is updated, and a quick search brought up "NPC table", showing me exactly what you saw. I'm not quite sure why the NPC table exists, when the pieces of data on it (NPC ID, sprite ID, and sprite color) could easily be put on the Bestiary for Elona and E+. Maybe someday that can be implemented.
It was meant to parallel the Item table: a plain list of technical info that the average player has little use for. Both are filed under the "Technical" category, it's just unfortunate that the NPC table shows up more prominently in search results than the Bestiary.
