Adding vertical space between rows

I am trying to create a mailing labels report but can't seem to get any vertical space between the rows. I see a cellpadding setting but nothing equivalent to cellspacing. Can anyone help me out?

Thanks.Try adding a text box, turning off can increase and can decrease in properties, under advanced, choose format, and work with the 'amount of space to leave on each side of report item.
Also try adding characters into the box, and set the color to be the same as background so that it is invisible.
