The last column is Master mode in a For the Worthy world.

Numbers are for one player, before Hardmode.

Coins: each kill rolls from 80% to 175% of this value. Rarer extra rolls can add more.

In a Hardmode world

In Expert and Master, Hardmode scales up weak enemies: those whose attack plus defense plus a quarter of life is under 80 (100 after Plantera).
