Can confirm this issue (and the workaround "tagged PDf" switch) on several versions of Indesign too. My case was not a table but a calendar made from regular text columns. Exporting to image or EPS shows no shift, while exporting to PDF with "tagged" off results in a triangular area where the letters shift more upwards the further the text is located to the right of the page, until about 80% width where it resets and behaves normal again. Attached for comparison: one export "font", one with "convert to outline".
