Table doesn’t work.

Hello there.

So I created a league, add all teams in it and created the table. But, I still don’t get how the table works. I thought the way it works is that if I edit one value (say the entire last games column for each team) the rest of the data in the other columns is automatically recalculated. Or does that sound too good to be true? So do I have to manually edit each cell in the table after each event? Thank you.
