Table that's just a big floor?

[Dabacabb]

I'd like to have a table that's just 1 huge, flat playing surface. Does anybody how to achieve this?

The playing surface on Gloomhaven Fantasy (scripted) is exactly what I mean (but it's a bit dark).
Alternatively, does anybody know how to load the Gloomhaven playing surface into other games?

Look for the Flex Table. It can be resized, and whatever its upper limit is, it's more space than the game itself allows access to.

if too lazy to figure out flextable:
whole room.
