Table row to SED?

thanks Omar.

I thought Iris would be part of a/the solution, but wasn't sure how
much of it is taken care of automatically.  Sounds like it still
requires a reasonable amount of manual intervention for now.
I'll keep an eye out for table.highlight.row capability sometime
in the future.
