- Sheet printOptions support added for: gridLines, gridLinesSet, headings, horizontalCentered, verticalCentered.
KNOWN BUG
New pageMargins and printOptions features do not work as expected. If you are using this version, then all page margins: left, right, top, bottom, header, and footer must be defined for each sheet. Otherwise Excel cannot parse the file. To disable printOptions, the attribute must be removed. Setting to false still enables the option.
