Margin Adjustment On Powertables

Hello,

I am using a power table to display several rows of data on a large overview screen. This works fine but part of what I am trying to achieve with this project is to make the headers have a smaller upper and lower margin whitespace since the margins that we are seeing on the screen are huge. Is there a way to shrink these margins on the screens? Looking through the Ignition documentation led me nowhere.

I am using 7.9 for this project.
