Hi,
here are some quick rules. It could be solved with fewer rules and also
with better or faster rules. You need essentially a rule for detecting
the structure and a rule for assigning the semantics. The rules would
also work if you have a plain text table with more rows.
Let me know if you have questions about some parts.
Best,
Peter
