Our exporter was writing all the cell properties in all cases, regardless of them being defined by the theme or not, and we shouldn't do that if we want the document to work properly in Word. To fix the issue I store the style-defined cell properties (the format of all four borders) in the table grab bag. The exporter recovers them and compares with the cell properties before writing them; if the cell property matches the stlye-defined one, we don't write it to the document.
