Is there a way to fix one or more columns in a tableviewer so that they
will remain on the left side while the user scrolls to the right?
thx, Friedhelm

Thanks! This is a great idea!
I have synchronized the 2 viewers.
Wondering if it is possible to hide the vertical scrollbar of the left
viewer and to make it look as if it is just one table...

This is a very sample implementation for a FixedColumnViewer. I'll keep
it in my samples area and try to make it behave better if I have time.
