I was happy to see that the M3 build of Eclipse 3.1 included support for a
virtual table viewer.
I created a Table object using the SWT.VIRTUAL style and attached a
CheckboxTableViewer to it.
When the table initializes, it's still taking a big hit because it appears
to be loading ALL of the items rather than what is initially supposed to
be visible (ie 12 rows instead of 100,000).
Have any of you experimented with this?

Eric,
You should ask this on the eclipse.platform newsgroup since that is where
jface questions belong. My guess is that this is either a bug or a platform
limitation, but I could be wrong.
