Part 1: Initial table setup - https://www.dailymotion.com/video/x7tzm81 Part 2: Making 8 tables - https://www.dailymotion.com/video/x7u240i Part 3: Final tables and method in action - here
To fill out the entire room, 2 special L-shaped bug tables must be created as shown in the video. This is because the game will delete any bug cages overlapping the east wall once you leave, which will make the bug table not work. Once you set it up properly though, you can easily make crowns without having to place crowns on the table ever again. It's 40 crowns about every 1.5 minutes, or 12 million bells about every 3 minutes with a trip to Nook's added in.

Q: I can't get two sharks/bug cages to appear. A: The sharks and bug cages can hang off the table to the east and south, not to the north and west. If you decided to do your table with sharks and cages hanging off a different way than in part 1, refer to part 4 above. If you try to hang an item off the wrong edge, it will create an invisible item instead which will interfere with your tables (see below or watch the video on fixing issues).
Q: What can I use besides crowns? Can I use NMTs/gold nuggets/clothes/pagodas? A: You can use any 1x1 item that can be placed on a table and is solid. That means no NMTs, gold nuggets, or other resources. The only clothing that can be used are headwear, accessories, and shoes.
Q: How do I use something other than crowns? A: Remove the sunken crown, then place another item in its place.
Q: What do I do if I don't have a shark model or katana? A: Lots of people are selling or giving away those, but you can also use the lab-experiments set which you sometimes find in the Nook shop.
Q: Help there are invisible items in my room/I can't place items on an empty table. A: Move your bug tables away, place empty tables in the suspected areas, leave the room and come back. The invisible items should reappear.
Q: Will this corrupt my save file if I leave the tables like this? A: No. You can save your game with the tables set up and they'll be there when you play again.
