Hi Mustafa,
thank you for the reply. I've filed a bug for the HeaderRenderer problem

I've seen that you already opened the bug 8735.

Betreff: [qooxdoo-devel] Some Table Issues
Hi all,
1.
We have discovered, that some tables in our qooxdoo app have heavy performance
problems while rendering.
After some time spend with debugging I found out that this only effects tables
with custom HeaderRenderer. It seems that adding custom Renderer to the table
columns produces many calls to the createHederCell function of the
HeaderRenderer. The time needed from the constructor call of the table to the
appear event of the table raised with 40 columns from 600 ms to 4 seconds...
I was able to work around this performance problem by implementing our own
class extending qx.ui.table.pane.Model. There I removed the
"headerCellRendererChanged" Listener inside the setTableColumnModel function.
It seems that we doesn't need this functionality. A HeaderRenderer never
changes after the table appears. It seems like a bug to me and maybe it is best
to add this listener after the table appeared. Should I file a bug report?
2.
In qooxdoo 4.0.2 and 4.1 the celldbltab event seems broken when the property
focusCellOnPointerMove is set to false. You have to do a triple click when a
row is not already focused. It worked with 4.0.1.
I guess it relates to the fix of
http://bugzilla.qooxdoo.org/show_bug.cgi?id=8735.

+1 vote for some core developer table love ;)
Best regards,
Andreas
