There are a few complications: The Pentatuch (Genesis through Deuteronomy) are actually a combination of writings from two eras, the latter contemporaneous with the Exile and return (appx 590 BC). So the table perhaps oversimplifies by listing only the earliest date. Another slight problem is that Isaiah is believed to be both pre-and post exilic (Chs 1-39 pre-Exile), Chs 40 - during Exile.
Regarding the New Testament, in the first table in the opening post I like the “early Aramaic version of Matthew” much better than what the scholars simply call “Q”. This would really be much of the material common to Matthew and Luke but not found in Mark.
I saw different references for the Old Testament too. Very interesting to me. And I think it had those two eras separated. I think it was on wiki
