Hi, Tom, thanks for quick reply.
I found interesting solution: instead of adding listener to label provider i've overridden TableViewer's handleLabelProviderChanged to call update with appropriate properties array, and everything is ok.
So I think default handleLabelProviderChange messed table up in some way (I think so because ViewerColumn's label provider listener called to it right after my custom label provider listener called update).
Going to file bug.
