[xep-support] XEP 3.7.7: Treatment of width="100%"

[Alexander Peshkov]

Hello Werner,

If you want to make sure that your table will fill all available space
just provide it with margin-left="0pt" margin-right="0pt".

Best regards,
Alexander Peshkov                             mailto:peshkov at renderx.com

WD> Thank you for the explanation Alexander.

WD> I have one more question though. If I remove the width specification the
WD> width will in fact become "auto". What can guarantee then that the area
WD> of the parent formatting object is filled up. "auto" means that all other
WD> constraints are taken into account. Couldn't this also imply that the nested
WD> table will be just wide enough to contain its contents? Isn't this left to
WD> the particular implementation? XSL Formatter, for example, does not make the
WD> nested table fill up the area, while XEP does.

WD> Regards,

WD> Werner.
