The following table presents the winners of the various international titles graphically. A coloured version is at http://homepage.ntlworld.com/andrew.j.simons/go/ProTable.html
Hyperpapeterie I don't know what you're planning, but if you're going to add the newer titles (Chunlan or BC Card Cup for instance) later on, that will be a huge pain. It may be better to figure out all the titles you need to include and lay out the table with them from the start.
Uberdude I was also planning to shade the cells the same colour for the same name and similar colours for the same country to make a nice visual chart, but it seems SL doesn't support that sort of advanced formatting.
valerio I think it is better to make a first table from 1988 to 9998 and a second from 1999. One table is difficult to read.
