To be honest, the first thing you said ("I cooked delicious meals for you, and all are on the table") is much clearer and better if you're referring to the taste & quality of food. The other sentences are more aesthetic presentation oriented. You could tidy the original line a bit, like: "I've cooked some delicious food for you. It's all on the table." or "I've made a delicious meal for you. It's on the table." There's nothing particularly wrong with these statements now, although I wouldn't personally speak so boldly or formally in such a context, but I might do it in a lightly humorous way, and I would speak a bit more meaningfully/descriptively, like: "Come get your chicken - it's on the table! It's the best chicken you've ever had. Gordon Ramsay can't do this."

- and all OF IT*^ is on the table

I like "I cooked a delicious meal for you. It is on the table." - best I set a nice table for you - means similar. "Nice" is an overused word. Try to find one more spoecific if you can. "Delicious" is good. I'd use "prepared" with "meal" or "food", but not with "table", unless you actually mean the table.
