I've been doing a stylistic overhaul of some daily checksheets we use for cross-checking data. The first three rows have been set as a Frozen pane so they remain at the top as you scroll, but ideally I'd like to change the colour of the divider in order to have it stand out less.
I've tried adjusting the bottom border of row three, but no matter what I do with it I'm still left with the black 1px line underneath it. Does anybody know of any way to change or remove it?
I note that this guy over on MrExcel.com once had the opposite problem of his Windows 7 theme over-riding the black and making it gray, but I can't find anybody else who's written about this.
Edit: Thanks to @jcbermu for the thought that if the line can't be changed, a top-down fill could be applied to the row above it. Though this doesn't change the divider, it can be used to fool the eye with the appearance of a line change, and at least allows departure from the stark black-and-whiteness of the default setting, assuming it is indeed impossible to modify the 1px line itself as @teylyn affirms. Will mark the answer as accepted if nothing else comes in within 3 days.
