Stymied

I love words.
To-day, in an article about the glitz less Golden Globe Awards, I came across the word
tablefuls
and my private little alarm bells went off.
Webster's will show it in its singular form, tableful, but no information on the plural.
Here is my conundrum; does it not make more sense to follow the form of say surgeon general, which in plural is surgeons general. After all the meaning of the word is full table or in plural, full tables, therefore the word, I think, should be
tablesful.
And does anyone except for this person really give a hoot ?
And should this person care ?
YES.
Because I love words and because there is a enough coarsening of the language going on.
And besides, it gives me something to do.
