I think Fulminato's proposal is sound.
It may also be good if we could keep resistances and immunities in some order, maybe mentioning biggest resistance/weakness first.
In general I think the enemy list is neglected because DukeLeto7 releases that enemy stats PDF regularly, so it's somewhat a duplication of effort. If we could get him to make a thread for that, and link to it from the top of the Enemies page, that would be nice.
Lore column is unnecessary but I don't see any harm since we have much more horizontal space on the new wiki. On the other hand, some of the quotes are rather tenuously related, and the Notes column could take up more space than it does now.
I feel enemy images are wholly unnecessary to be honest, and players can just look them up by name. They add "spice" to the Bosses page, but for the Enemies page I think it is not a worthwhile use of vertical space (or our host's disk space). Unless anyone objects, I would propose to remove and delete them.
Or rather, players could look up enemies by name if the enemy tables weren't collapsed by default. That should also be changed,
