Planning for the solution may be simplified if we observe that in the two large tables (both preceded by "Conversion for a certain paragraph or table cell:") the writing direction of the document (first column) is irrelevant, having no effect on the outcome case (last column). Thus, the first column and the entire last half of the tables can be omitted.
Likewise, the origin ("Inherited from style") of the direction attribute seems irrelevant, and need not be called out. This eliminates a couple of rows. --TJ (Talk | Contribs) 18:33, 27 July 2010 (UTC)
Thank you very much for your feedback.
Yes, the tables could be simplified, but not as far as you proposed. The first column makes the difference for the cases in which the writing direction of the document and the paragraph/table cell differs and the text alignment value is inherited from the style. I will update the tables today. Looking forward to further feedback/comments/improvements/...
