[flexcoders] Eliminating Horizontal scroll on AdvancedDataGridColumn

[yossi.baram]

Hi,
How do I eliminate horizontal scroll on AdvacedDataGrid columns?
If I set horizontalScrollPolicy='off' to the datagrid it eliminates the 
scroll for all grid, I need the same thing but for each of the columns.
I build the columns dynamicaly in my AC

var column:AdvancedDataGridColumn = new AdvancedDataGridColumn();
column.width=100;
columns.addItem(column);
column.headerText = 'xxx';
column.dataField = 'test';

What should I set to the column object to disable scrolling?

Thanks

Jo
