Right align numeric column in TreeView

I have a simple tree view with which has numeric data in the last column, which I would like right aligned.
This is the XML I’m using so far

                <child>
                  <object class="GtkTreeViewColumn">
                    <property name="title" translatable="yes">Elevation</property>
                    <style>
                      <class name="right"/>
                    </style>
                    <child>
                      <object class="GtkCellRendererText" id="a-elev-renderer"/>
                      <attributes>
                        <attribute name="text">4</attribute>
                      </attributes>
                    </child>
                  </object>
                </child>
              </object>
            </child>

Neither GtkTreeViewColumn nor GtkCellRendererText have a CSS node and there seem to be no alignment properties available to set in the xml.

All GtkCellRenderers have a xalign property, set it to 1.0 for right alignment:

<object class="GtkCellRendererText" id="a-elev-renderer">
  <property name="xalign">1.0</property>
</object>

Thanks for that. Looked everywhere and googled everything imaginable and found no answers. So simple once you know.
