A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Well, I've learned a little more about this situation. For whatever reason, if I only format one cell at a time, the pivot preserves the formatting, but if I select more than one and format all selected cells at one time, it seems clear that formatting on refresh.
I've tried this multiple times, and it seems to be repeatable. I really hope there's a fix for this. If you tell me that, after so many years of being able to format column headings all at once, that I have to select one cell at a time and format each separately, I'm going to be really disappointed.
