As you can see, the 2 block workbenches from Immersive engineering are too big to fit inside the 1 block trading posts.

Could you make it so that the workbench is aligned in the center instead of on the side?

Or could make them smaller so they fit inside the block?

For these tables, the game considers only half of them as the actual workstation, so the villager would need to be off-center for it to fit inside without further scaling.
