The main configuration of the iSheet
All columns and their configurations
All views and their configurations
Any sections and the order of columns
Lookup columns are preserved in deployed templates but in most cases must be re-created if you wish to link to another source iSheet, as the lookup column source sheet is a configuration that cannot be changed once created
Join columns are preserved in deployed templates, but may need to be modified to point to the appropriate iSheet in the column list of sheet configuration, and the join condition updated, as needed
