In the beginning there was a table...

It all started with tables. Some of my readers probably still recall all those huge sheets of paper, precisely carved with lines, used to store all operations of whole companies. In Poland, where I come from, we usually called such written records "gallows". Name came for the usual T shaped lines, dividing columns into Credit & Debit sides, with amounts hanging below.
You can still see little faded resemblance of those records in lot of financial reports, produced by modern accounting software. Especially clear when you export such reports to Excel. By the way, that same application has prominent place among most frequently used by financial world. Yet so many of us are not aware of revolution, which lies in very heart of worksheets. Today I would like to catch your attention to very special kind of tables, which can make your life much easier in different ways.
