Since cellpadding is not supporting in HTML5 you should use CSS

Thanks Scholle, it actually turned out to be the border-collapse:collapse; setting that made the difference, but what I was doing wrong was applying it to the individual cells rather than the root table itself!Looking at information on wc3schools (below) it seems that the cellspacing and cellpadding are html settings and dont apply to CSS settings. Although I did find somewhere that cellspacing is valid if you have border-collapse:separate; set in your CSS... but i cant find that reference anymore!Ref:http://www.w3schools.com/tags/att_table_cellpadding.asp Good luck with your project too, its been good to talk,J2010/1/23 mst...@googlemail.com <mst...@googlemail.com>
Hi John,
my name is actually Matthias, but I prefer using Scholle...
Anyway, thanks for the feedback. I think I know what I need to know
and will get this done next week.
Regarding your problem with the gaps. It's a typical cellpadding /
cellspacing problem.
Thanks to the Firebug guys, I just looked at your DOM representation
and found that there are 3 three tables with class "daygrid" (table
for days, table for employee/owner, table for the main grid itself).
All three tables missing the two attributes cellpadding="0" and
cellspacing="0". Add them and you are where you want to be...
Good luck...
