Create table from template is not an option for creating a table through the Guided Application Creator. The other options are available for creating a table in the app. Upload spreadsheet allows you to import data from an Excel file and create a table based on the spreadsheet columns and rows. Extend a table allows you to create a child table that inherits fields and behaviors from a parent table. Create table from scratch allows you to define your own fields and data types for a new table. Reference: Create tables
