Code used to return the last programmatically set width value instead of the real column width which could have been changed by user if the column was resizeable, fix this by returning the current NSTableColumn:width value. Closes #11397. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@62516 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
