tableview column width to minimum size.

[Young]

        I have set up a filter in table view as in 
http://apache-pivot-users.399431.n3.nabble.com/Filter-in-TableView-td3215369.html
        But, I cannot set the width to "-1" in bxml configuration
because column widths of the filter part becomes 0.
        So, I am trying to double-click the grid on column header from Java
code. I have no clue how to do that in Java code. Is it possible?
