Placing a table in CasinoCore is simple, you have to place a sign and write in this format:
line 1: [casino], line 2: game name, line 3: amount of sits (each game has its own limits make sure to check in the game list how much the game you want has), line 4 (optional based on the game): additional value the game my request (check game list)
after writing everything you can simply destroy the sign and it will automatically generate the table, to remove the table shift and right click on the middle of the table.
