Yes, table->chidren is a list of GtkTableChild structures.

Do something like:

GList *list;

for (list = GTK_TABLE (table)->children; list; list = g_list_next (list))
  {
    GtkTableChild *child = (GtkTableChild *) list->data;

    if (child->widget == (GtkWidget *) separator)
      {
        /* found it */
      }
  }
