Grand Gourmet walls, deck and themed tables (Marine table)
Quick answer
The floor you lay decides everything: dining-room flooring makes an inside room with walls, deck flooring makes open deck with none, and a themed floor turns the tables on it into that theme. To get a Marine table, place Marine floors around a regular table; other themed tables work the same way.

Inside, outside and walls
You don't place walls yourself. Gamers Heroes' review says you pick a floor tile and cover the floor with it, and the walls, ceiling and exits appear around it. On the Steam forum a player explains the same rule: lay the dining-room 'flooring' where you want walls, and 'deck flooring' where you want them gone.
Items marked (Deck), or shown with a fish icon, are meant for outside, another player adds.
A request for a Marine table doesn't mean buying one. A player on the Steam forum says to place Marine floors around a regular table, and it becomes a Marine table. Gamers Heroes' review describes the same thing for whole areas: cover an area in a themed floor such as Thriller Bark and the tables in it convert to that type.
Another player says the other themed tables work the same way: each decoration shows its theme with an icon and a short description, so match the floor and decorations to the table you want.
Themed areas also draw certain customers: the review names Skypiea and Thriller Bark areas as ways to bring in particular characters.
