I'm not sure why you want to use tables rather than having a separate header for that section. You could simply have everything in the header on the left or right margin or centered. Use of the StyleRef field will pick up relevant document content. Sections / Headers and Footers

The tables will adjust, assuming that you want headers and footers on the wide edge of your landscape pages. If they are turned sideways for printing, though, it will look strange. See Portrait page number on a landscape page.
