Listview Alignment, Vertical & Horitzontal Spacing

I have a listview that will always be 4 rows and 5 columns however font size can change but I'd like to do some formatting with alignment.

I know I can change the width by changing columnheder width and
I know I can center align column header like this:

Code:

---

columnheader.Width = 200
  columnheader.TextAlign = HorizontalAlignment.Center

---

However setting the listview.Alignment property only gives you top, left, default and snap to grid.

I want to be able to center the listview data both horizontally and vertically. Also, Is it possible to increase vertical spacing (change row height without increasing font size) without adding blank rows???

I use View.Details. I tried messing with tiles but it didnt seem to do what I expected.
