Customizing forms problem

Hello Everyone,
I am trying to improve the forms I am working with and would like some help.
I am stuck with a quite simple problem.
I would like my two buttons to be aligned to the right of the form.
I thought I could do it with columns, but that didn’t seem to help at all.
Here are some pictures. I hope it’s clear what I’m trying to achieve.

Thank you for your help and suggestions!

Not sure about using Columns, but this is achievable by using table:
RightButtons.xaml (14.1 KB)

Thanks, this helps, but still not the best solution I think.

Came to this even though I have 8 columns there and the buttons should be squeezed together.
