In your Seating Arrangement page, click on "Edit Seating List"
You can quickly update the tables' names and seats capacity, as well as assign a color to your table so that you can realize your tables visually together.
If you want to add new tables, select the number of tables you want to add and the seats capacity of each, then click "Go"
The new tables will be added to the end of the list. Hit "Save" to save your changes and return back to the Seating Arrangement page.
