## (aral-matrix) 07 April 2025 - Demo10: added a disabled use of borders with merged cells
* enable Demo10 line 450 to experiment - but LibreOffice behaves weird (at least) with (diagonal) borders, so I have disabled this Demo functionality by default
## (aral-matrix) 24 March 2025 - XLStyles: XLFont fix attribute values underline, scheme, vertAlign
* getters ```XLFont::underline, ::scheme, ::vertAlign```: fix default value to set for attribute val when tag doesn't exist
* setter ```XLFont::setUnderline```: return correct "none" value for XLUnderlineNone from XLUnderlineStyleToString (was returning empty string)
