Unfortunately, that doesn't help me. I'm not trying to modify the column, 
but the header of the column, and more exactly, the distance between the 
label and the edge of the button. I've managed to modify the size of the 
button, but not the padding :(

This is what I've been doing:
//nothing changes
(column.Widget as Label).Ypad = 0;

Gtk.Box box = (Gtk.Box)column.Widget.Parent.Parent;

//nothing changes
box.Spacing = 0;

//it works, doesn't do what I want
box.HeightRequest = 10;

//doesn't make any difference
box.SetChildPacking(column.Widget.Parent, false, false, 0, Gtk.PackType.Start);
