Agreed - I'm a heavy Excel user and I use tables for 90% of data. Tables enforce unique column names, what is missing is the same for unique row names or ids plus an easier way to relate rows, without having to use index match everywhere, which soon becomes a real pain in the arse. A separate me product - power pivot does something like this - ms needs to add this as native functionality to Excel, since normal pivot tables are so unflexible, I never use them anymore.
