Can I copy a single table structure from Application A to Application B?

Keep in mind that if you actually do a move on the table it will destroy the original table and move it to the new app and it will lose all its relationships.

If you were going to use that method you would first want to copy the app and then move it.

The other way to do it is there is indeed a new option on the table homepage for a table to copy this table and it will let you copy it to another app as long as the owner of the app is the same for both the old and the new app
