Cell height applies to all rows of the data table, and Display Width applies to a specific column.
dt = current data table();
w = :Height << Get Display Width;
:Height << Set Display Width( 2 * w );
ht = dt << Get Cell Height;
dt << set cell height(2*ht);
The above JSL will change the display width of height to twice its original width,
and the rows height to twice its original height.
