Styling doesn't work properly in excel 2007?

Hi!

I've had some problems with styling from some reports I'm doing in Excel. The reports was made in Excel 2003 where it worked fine but when I got 2007 it started acting weird (.. and random). As you see in the attachment (I've modified the colors to make it more "view" friendly) in to bottom there suddenly is a white line above the black border but not all the way through (this is in print preview, the "error" is not when I'm in the spreadsheet). What makes it even more weird is that when I print it, the white "line" above the border becomes grey so that the bottom border is "fatter" the first centimeter and thinner for the rest.

I've tried a lot. But maybe you guys have experienced the same? I know it's a small thing, but it really started to freak me out that my spreadsheet isn't "what you see is what you get"-ish.


I also experienced that the borders around graphs got fatter, but that I could correct just fine.


Thanks in advance!
