This seems to change the address for heroes and (when there is an option for it..) fleets. That means, if you play with stock skins, the table may not enable for you as it is looking for the skin enabled code and it isn't going to be present in your game. So no table for you.
I have tested this only with United Empire and Vodyani starts, so I can't promise that it will work with other factions with DLC skins enabled or not. But for United Empire especially, you need to enable the skins at game set-up and then follow the table instructions to get the script to activate.
EDIT: Further, the table will not activate if you start a new game, quit to main menu and start another game. Even if you didn't activate the table first time around. It must be a fresh start, no start position scumming

The table also doesn't seem to activate for custom races. Atleast, for my custom United Empire at any rate. Ymmv.
