There are a couple of ways of displaying data in an adf table if its not bound to a database.
1. You can create a programmatic view object and populate it at run time(i.e. click of a button) and display the view object as a table.
2. You can create a list of POJO objects and populate your adf table programmatically.
By the way from where are you getting the data. Can you explain your use case a little more?
Hope it helps.
