This AppleScript is pretty basic; it was built for converting the awfully verbose tables OmniPage Pro 11 will export when you export as Netscape 3.2 HTML (this is the best of the worst export modes). Thus, export your tables thusly, and this script will make them more reasonable. I built this script while transcribing an alluvion of tables in Soviet Union: Facts, Descriptions, & Statistics.
