Repeating a Tablix Column Headers on each Word document page

Hi SSRS Masters!

I have a report that I need to import into a Word document.  One of the requirement is to have report column headers to be repeated on each page of a document. I set the Tablix properties to 'Yes'  for 'RepeatColumnHeaders' property for Page Break group but it does not work.

Is there something else to set for 'Row Groups' and 'Column Groups' to get report column headers to be displayed on each page of  a Word document?  Please see the image below for reference.

Thanks a lot for help!!!
