You could use append_column_numeric() instead of append_column().
http://library.gnome.org/devel/gtkmm/unstable/classGtk_1_1TreeView.html#ae6fc0051cc178bfacea2dec27c2d5a58

These are both convenience methods. If neither is enough, you can
instead specify the cell renderer details explicitly:
http://library.gnome.org/devel/gtkmm-tutorial/unstable/sec-treeview.html.en#treeview-cellrenderer-details

By using set_cell_data_func() you can create a string representation for
our numeric value:
