Thanks for your code
I think I can get the vertical scrolling to work by adding an extra row a=

t 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 automat=
ic 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. S=
o, I see 0 through 25, then 1 through 26, then 2 through 27, ..., then n th=
rough n+25. So, I was wondering if it would be possible to be able to see m=
ore than 25 rows at a time apon a resize via a mouse drag.

Aaand ...

He ignores the question again.
