Combining vertical text direction of page with ‘right-to-left’ text direction of a table

[Regina Henschel <rb.henschel@xxxxxxxxxxx>]

Hi all,

I’m on working to specify the property “style:writing-mode” for ODF. 
That property is called “text direction” in the UI of LibreOffice.

A page in a text document has the setting “Text direction” in section 
“Paper Format” on tab “Page” of the “Page Style” dialog. Possible values are
Left-to-right (horizontal)
Right-to-left (horizontal)
Right-to-left (vertical)
Left-to-right (vertical)

A table has the setting “Text direction” in section “Properties” on tab 
“Table” in “Table Properties” dialog. Possible values are
Left-to-right (LTR)
Right-to-left (RTL)
Use superordinate object settings

LibreOffice can combine a vertical text direction at the page with RTL 
text direction of the table.

Are such combinations actually used in documents?
Does LibreOffice render the texts in the way users need it?
What is the intended behavior of such combinations?

Kind regards,
Regina
