Data Entry - typing list of sequential numbers (very easy!)

This is very simple, I just don't have time to do it myself. I have a iWork pages file, so this is for a mac user. I've started to create 1000 printed labels ... 1 to 1000. I need someone to finish this, either by typing them in manually (pressing tab takes you to next cell)... or setting up rule to do it automatically (which I don't know how to do). Should only take 30 mins to do manually, less if you know how to do it with a rule. numbers need to be in correct position (already positioned), and same size font etc..
