Delete single newline between tables

Tech-Archive recommends: Fix windows errors by optimizing your registry

I'm fighting with a document automation system and can't seem to get
what I want from it directly, and am trying to switch over to
attacking it from the post processing side. The closest I can get the
tool to produce to the desired output is a series of single row tables
with a single newline between them.

Can I write a macro to detect that pattern and delete the new line
(merging the single row tables into the complete table I want)?
