Thank you @karthikpandelu for your work and helpful comments!

@kevinrushforth mentioned this is a know problem with Swing interop on Windows (do we have a jira ticket?), can be ignored for the purposes of this PR.

made some changes, please take a look.

There is no such policy (neither here nor in JTable).  I suppose it is possible.  I find the other policy CONSTRAINED_RESIZE_POLICY_ALL_COLUMNS is less useful than the the new default policy CONSTRAINED_RESIZE_POLICY_FLEX_LAST_COLUMN - something about changes applied from left to right feeling more natural.
