Section breaks when generating to Word can be difficult to fix. You have to be generating to a Word template rather than using the CSS option in the Printed Documentation dialog.That template has to be set up to work as you want and even then it can have a mind of its own.

There are Word macros on my site. See Format Tables. You might be able to adapt that to help.
