I am working on a form with a grid or listview which will show data from a related table as a lookup and I would like to show a descritive fields instead of the Foreing Key field value, how can I do this?

In the picture attached, the FK_Appliances in the Grid or Appliance in the List View are the ones I want to show the descriptive field instead of the FK value.

Also, since I am learning SF, I found that the creation of a ListView is a bit difficult than using a GridView for read only data, is there a way to show the grid with empty columns like in the ListView in order to cover the gray area of the grid?

Thanks!
