Hi Clemens,
I am also experiencing the TableView slow vertical scrolling issue with large
number of columns.
Did you manage to work around this issue with a code change in TableRowSkinBase
as you mentioned in your bullet point 2 and if so could you share what you did?
Thanks

Hi Clemens,
Thanks very much for your message, it definitely helped me crystalize the root
of the issue beyond my previous understanding, and also gave me some additional
options on how to work around it :)

Doesn't ControlsFX have that already, or some other 3rd party library?
Yes ControlsFX has a GridView class. But it is based on Skin in
"com.sun.javafx" packages (replaced by "javafx.scene.control.skin"
packages since JavaFX 9). I have not tested if it would still work with
JavaFX more recent

So might it be better to submit a new feature request to develop a separate and
leaner control entirely, geared much more towards viewing large datasets
without all the bells and whistles of a TableView?
Hi Martin,
Big thank you for your message, and for sharing your code. I took a look and
it could definitely be a great starting point for me. The content we need to
display is very simple, every cell just needs to display text, occasionally
with an expand/collapse button on the left. So I

Hi Kevin, Nir,
I also dug out those two bug reports and agree neither are close enough.
However, it seems to be general consensus that in order to properly address the
issue, TableView's virtualisation would need to be changed to support columns
in addition to rows, and that the extra
Hello Ed
At the center of our product is an extension of the TableView control that's
responsible for displaying all the output from our pivot reporting engine.
Depending on how the user configures the layout of their pivot reports,
sometimes there are a legitimately large number of columns
I took a quick look and didn't see one that was close enough to this, so
I think it's worth submitting a new bug report. The closest I found were
JDK-8166956 [1] and JDK-8185887 [2].
I also would be interested to know whether others have run into this in
their applications.

Hi Ed,
Try to search JBS [1] for this issue. If you don't find one, you can submit
it through bugs.java.com, though I suspect this is known.
I don't know the technicalities of VirtualFlow in TableView, so can't help
there.
