col.Alignment = 1.0f;	// col title right aligned
colr.Xalign = 1.0f;	// render data right aligned

Depending how your data is stored in the model you might also need
 
col.SetCellDataFunc(colr, new TreeCellDataFunc(ShowExpense));

and

void ShowExpense (TreeViewColumn tree_column,
   CellRenderer cell, TreeModel tree_model, TreeIter iter)
{
  double x = (double) tree_model.GetValue(iter, 1);
  ((CellRendererText)cell).Text = String.Format("{0:N2}", x);
}

or similar.
