here's a little something to help you get started.
//Make an example table
dt=New Table( "Example",
	Add Rows( 5 ),
	New Column( "Column 1",
		Character,
		"Nominal",
		Set Values( {"alpha", "beta", "gamm", "delta", "ice-cream"} )
	)
);
//get the value of the first column in dt, at the 5th row
nnn=column(dt,1)[5];
//make a new useing the value obtained above
dt<<new column(nnn);
