Add an option to set header on border (style) (#9920)

fix #9796

Sorry that you've had the issues.
I've actually encountered them yesterday too (seems like they have
appeared after some refactoring in the middle) but was not able to fix
that rapid.

Created a bunch of tests.

cc: @fdncred 

Note:

This option will be certainly slower then a default ones. (could be
fixed but ... maybe later).
Maybe it shall be cited somewhere.

PS: Haven't tested on a wrapped/expanded tables.
