Overview

Note:

The recommended way of managing header/footers is via Worksheet#header_footer

Header/Footer options for printing a worksheet. All settings are optional.

Headers and footers are generated using a string which is a combination of plain text and control characters. A fairly comprehensive list of control characters can be found here: https://github.com/randym/axlsx/blob/master/notes_on_header_footer.md
