I believe you saw something similar to the app 'What's new in QlikView 11' in the reports tab.
You can try or dowload it ( it you want to reproduce it, you need to download to analyze it better...)
Instead of a table box, it is a straight table.
The dimensions ( and expressions ) have enable conditions based on the selection of fields with all dimension and expression names.
If you have more questions about this object you can ask here again.
Hope it helps for now,
