Yes, I meant GtkTreeViewColumn.

    GtkCellRenderer *renderer = gtk_cell_renderer_text_new ();
    GtkTreeViewColumn **test_col = g_malloc (sizeof (GtkTreeViewColumn 
*) * 2);

    test_col [0] = gtk_tree_view_column_new_with_attributes ( "test0", 
renderer, "text", 0, NULL );
    test_col [1] = gtk_tree_view_column_new_with_attributes ( "test1", 
renderer, "text", 0, NULL );
    gtk_tree_view_append_column ( target, test_col[0] );
    gtk_tree_view_append_column ( target, test_col[1] );

    GType string_type = G_TYPE_STRING;
    GtkTreeIter current;
    GType *types = g_malloc (sizeof (GType) * 2);
    types [0] = G_TYPE_STRING;
    types [1] = G_TYPE_STRING;
    GtkListStore *list = gtk_list_store_newv (2, types);
    gtk_list_store_append ( list, &current );
    gtk_list_store_set ( list, &current, 0, "test00", -1 );
    gtk_list_store_set ( list, &current, 1, "test01", -1 );
    gtk_list_store_append ( list, &current );
    gtk_list_store_set ( list, &current, 0, "test10", -1 );
    gtk_list_store_set ( list, &current, 1, "test11", -1 );

    gtk_tree_view_set_model ( GTK_TREE_VIEW ( target ) , GTK_TREE_MODEL 
( list )) ;

I made the GUI in Glade.

gtk_list_store_set ( list, &current, 0, "test00", -1 ); was previously 
gtk_list_store_set ( list, &current, 0, "test00", 1, "test01", -1 ); and 
gtk_list_store_set ( list, &current, 1, "test01", -1 ); didn't exist.
