Overview

Note:

The recommended way to manage page margins is via Worksheet#page_margins

PageMargins specify the margins when printing a worksheet.

For compatibility, PageMargins serialize to an empty string, unless at least one custom margin value has been specified. Otherwise, it serializes to a PageMargin element specifying all 6 margin values (using default values for margins that have not been specified explicitly).
