This is super helpful! I've been wrestling with table formatting in Word for ages, and those pesky lines always seem to defy my attempts to remove them cleanly. Your guide will save me so much frustration, especially when dealing with the more finicky elements like getting rid of individual borders without making the whole thing look like I've got Ragdoll Archers messing with the layout.
