You should see the gtk examples, that come with gtk.
There is a table example in there. That is the best 
place to start learning gtk.
 
I suspect you are changing row with columns, see this example:
Carlos
---------------------------------
table = gtk_table_new (1, 7, FALSE);
gtk_box_pack_start (GTK_BOX (hbox), table, FALSE, FALSE, 0);
gtk_widget_show (table);

label = gtk_label_new ("Color");
gtk_table_attach (GTK_TABLE (table), label, 0, 1, 0, 1, GTK_SHRINK, GTK_FILL, 5, 0);
gtk_widget_show (label);

label = gtk_label_new ("r");
gtk_table_attach (GTK_TABLE (table), label, 2, 3, 0, 1, GTK_EXPAND, GTK_FILL, 5, 0);
gtk_widget_show (label);

label = gtk_label_new ("g");
gtk_table_attach (GTK_TABLE (table), label, 4, 5, 0, 1, GTK_EXPAND, GTK_FILL, 5, 0);
gtk_widget_show (label);

label = gtk_label_new ("b");
gtk_table_attach (GTK_TABLE (table), label, 6, 7, 0, 1, GTK_EXPAND, GTK_FILL, 5, 0);
gtk_widget_show (label);
