Considering the following MWE, I would like to know how I can get the table
inside the item to be aligned with the item. It seems the tabel takes the
width right, but it gets pushed to the left, disregarding the item's
indentation.

I think I read about this behaviour somewhere, but I have spent 4 hours
looking for it in the manuals and I can't find it. :(

Any help would be appreciated.

“You develop an instant global consciousness, a people orientation, an
intense dissatisfaction with the state of the world, and a compulsion to do
something about it. From out there on the moon, international politics look
so petty. You want to grab a politician by the scruff of the neck and drag
him a quarter of a million miles out and say, ‘Look at that, you son of a
bitch.’” — Apollo 14 astronaut Edgar Mitchell
