The best answer I can give you is, Latin - "Table" is derived from the classical Latin word "tabula."
Maybe it got its name because it's a structure that you can place things on, stack neatly, easily organize...and all the other good words in the language were taken already!
That's like questioning why the letters of the alphabet start with "A-B-C" and not Q-W-E" :-D
