[flexcoders] DataGrid: How to Prevent Extra Space Allocation to Last Colum

[Dharmendra Chauhan]

Hi All,
    Please help me to get rid of extra space being allocated to the last column 
of DataGrid.
 Where does this extra come from ? whatever column I resize should actually be 
resized.Why does one column resize led to last column resize ? 

I have set horizontal policy to auto and resizable = true for all column.Also I 
cant make resizable = false for last column as It is not acceptable to my client

Any help would be appreciated.
