How is a table layout built on a floor grid?
A table layout is built in the Biletora panel by entering the number of tables and each table's capacity onto a floor grid. The system sets the grid size automatically based on the table count, places the tables on the grid, and lets you mark which direction the entrance faces. Each table has a gridIndex value that represents its visual position in the hall. The floor plan is thus set up against the real venue layout, and guest distribution is done on top of it.
