There can be several columns just for a single cell renderer.
Those are the column numbers, I use the next enum for a gtk list store:

enum
{
COLUMN_VALUE,
COLUMN_TEXT,
N_COLUMNS,
};
store = gtk_list_store_new (N_COLUMNS,
G_TYPE_INT,
G_TYPE_STRING);
cell = gtk_cell_renderer_progress_new ();
gtk_tree_view_insert_column_with_attributes (GTK_TREE_VIEW (treeview),
-1, "progress", cell,
"value", COLUMN_VALUE,
"text", COLUMN_TEXT,
NULL);
GtkTreeIter iter;
gtk_list_store_append (store, &iter);
gtk_list_store_set (store, &iter,
COLUMN_VALUE, 40,
COLUMN_TEXT, "blah", /* see
http://library.gnome.org/devel/gtk/unstable/GtkCellRendererProgress.html#GtkCellRendererProgress--text
*/
-1);
Voilà, something that uses these function.
