We have a locked column with 0px width ( { locked : true, width: 0}) which was working correctly in RC1. However, after we upgraded to RC2, we see the following: Width0.png
notice the phantom column width between "Budget" and the "Test User" column.
However if I update the config width to 1 ( { locked : true, width: 1}), I then get this: Width1.png
which is a lot better but still got that annoy 1 pixel border between Budget and Test User.
