Row height and highlight

I created an application where the Orientation is set to “Editable grid (view)”.

I found a few example of how to change the row height in a grid to make the rows tighter together.

I made my own theme using the BlueBerry as a starting point. Then I made the changes described. However, the row seems to still be the same height and the alternating colors of the rows (odd/even) do not seem to take effect either. All rows background colors are the same.

Any suggestions?
