I have a request for a custom header in Excel and I'm having a hard time
getting what I want.

When I type the text into the section of the header I want it to appear in
and format it the way I want, it looks completely different when I leave the
cell. Mainly the font size and the line spacing gets wacky.

Also, there's not enough room in the header for the number of lines I want
in the header, can I make it bigger?

I thought maybe a graphic of the information I wanted to place in the header
was a good option, but I need it to run the width of the page and it only
goes as far as whatever section I use to insert it. Is there a way to
combine the sections?

Any help appreciated. Thank you
