I was assuming inside, but I hate to give advice based off assumptions.
I think it might work fairly nicely inside for a smaller table. 6'x3' puts it at the smaller end, but I have a baby being housed in one that size and it works nicely for him.
If you go this route I'm curious as to how it works for you. Seems like it might work nice. Might have to remember this next time I get a hatchling.
