To save as much space as possible, I adjusted the height of rows in a way that there is only a small space between text and upper and lower cell border. When printing, for some rows this space becomes bigger and I don't know why and how to avoid that. This happens to rows with wrapped text (but only to some, not to all cells with wrapped text). This "change" is already visible in the print preview but not in the page break preview.

Does anybody knows the cause for this and how to avoid it?

Thank you.
