Collapsing a Row in a Datagrid

[Ray]

Does anybody know of a single line of script I can use to set the height 
of a single row in a data grid?

My data grid's style is table and I've already set the dgProp["fixed row 
height"] to false.  Now I'd like to set the row height of a single row 
to 0 or 1 or something to simulate collapsing the row.

Thanks,
