Which Gnostic books "were destroyed by the Church"? And, why is it that what the Fathers said about the Gnostic can't be trusted?
To answer your question, I can't. The table seems to be a distillation of what the author says in the book. Fortunately, the book is online in Google. The table is found on Chapter 10 and may be accessed here.
Check out also the Bibliography and the chapter notes.

Not just Gnostic books, Teofilo, all non-orthodox books. There are no Arian writings that survived, no Pelagian manuscripts. We only know about Arian beliefs and Pelagian heresy from their accusers, as they paraphrased them. The Book of Enoch, which was originally red in churches and was very popular among early Christians (and is in fact part of the canon of the Ethiopian Orthodox Church) has been destroyed to the last copy at least in Greek and Latin versions, etc.
Even Gospels whose versions did not conform to the 4th century orthodoxy as established by the First and Second Ecumenical Councils and the subsequent late 4th century Christian canon, have disappeared. We know they existed indirectly from quotes of various Christian writers who quote from Gospel versions no longer extant. An example is Eusebius, who quoted Matthew's Great Commission no less then 17 times without the Trinitarian formula prior to the First Ecumenical Council and five times with Trinitarian formula following the Council.
Thanks for the links. I will review them.
