My example starts with 100 rows, numbered 0 .. 99; added rows are numbered 42. I don't recall the numbering used in your examples. Apropos to this, I would reiterate Lew's question about your now deleted examples. As Joerg Meier helpfully observed, they can be retrieved from one's NNTP server, but you might clarify your preference. > (3 When I, myself, do begin to add more code to this project where > should I be concerned about exceptions occurring.

Without context, the short answers are these: don't swallow exceptions and don't block the EDT. -- John B. Matthews trashgod at gmail dot com <http://sites.google.com/site/drjohnbmatthews>

Thanks for your code

I think I can get the vertical scrolling to work by adding an extra row at the very top of the two tables. I'll then insert data into that empty row and create a new empty row each time after I add the data. So, the automatic vertical scrolling will never show the empty bottom row.

About only showing about 25 rows. I meant to say that the scrolling works. I do see all the rows created, but the project only shows 25 at a time. So, I see 0 through 25, then 1 through 26, then 2 through 27, ..., then n through n+25. So, I was wondering if it would be possible to be able to see more than 25 rows at a time apon a resize via a mouse drag.
