Creating a “Horizontal” table in a Report

Ok yesterday i got a request for a report, our customer wants the same report as usual just data and some percentages over a total. Piece of cake, but then “Ow yeah he wants them over a dynamic amount of Countrys shown horziontally”. My heart dropped. Horizontal tables .. in reporting server .. no way.
So when i got back to my workplace i started googling inmediatly, after some fruitless attempts i found the answer with the reporting master Chris Hays (the founder of RDL):
So it seems with some hacking horizontal tables are posible!  Works like a charm now.
