Hello,
You're most welcome. Thank you for a great product.
Also, I noticed that the second issue (issues with dropping of rows) basically resolves itself when there is some distance between the tables. On my initial test, the table borders were touching, and I think this led to the drop zone confusion. From debugging, I could tell that the error occurred when I was actually dropping a row from #1 to #2, but the drop zone fired table #1 or #3.
When I integrated the tables into a more realistic design (e.g. with space between the table borders), I have had no further issues.
So, thanks again.
