Webkit based browsers display table head incorrectly
Site in question: http://www.sysar.be/home.htm
If you open this website in any Webkit based browser, you'll notice the mistake on the middle table's head. It renders correctly in all versions of IE, Firefox and Opera. The website was created in 2001 so it's old in design (and needs updating) but still, if all other browsers render it correctly something must be up. Is it my mistake or is it a bug? I'm not too experienced anymore but if someone would just give me a clue where to search then I could add code for Webkit based browsers. It seems Webkit based browsers just ignore the width property I'm giving to the cell. You'll find the code of the middle table at line 408 in the source.
Thanks in advance
