Dear Alain. > I think we should update the actual content based on the actual Trac > default wiki syntax, or if there is another way to make it ... I have tried to add some HTML code. Take a look at this example: https://projects.centos.org/trac/artwork/wiki/DistroDesign/Wallpaper As <style> definitions are not accepted I have to use dirty tricks to adjust table borders. I wonder if this really makes sense. Maybe we should just stick with the capabilities of the Trac wiki (which definitly means col/rowspanning is impossible) and re-work the content.
