Hi Igor, Thanks for that nice explanation. It's totally clear now. I've added a wiki entry under
http://www.wicket-wiki.org.uk/wiki/index.php/Reference_library#Wicket_reference at http://www.wicket-wiki.org.uk/wiki/index.php/Tablesandgrids It is still very rough, but that's all the time I got today. Can you check and change where necessary.
