Usually (but not all) inuts script have two tables, first: 70-72 bytes, second 33 or 65 bytes.
This second table is public key? Where this is in Bitcoin documentation?

I am also unable to find Bitcoin documentation. Do let me know if you find the answer.

Hi,

Yes : for spending an usual P2(W)PKH, the input(/witness) is

Code:

Because the locking script (scriptpubkey/witness program) is in this case

Code:

OP_DUP OP_HASH160  OP_EQUALVERIFY OP_CHECKSIG

Once having verified that the public key matches the hash in the locking script, there is only OP_CHECKSIG left, which takes and verifies that the signature matches the public key.

You can find more about OP_CHECKSIG on the wiki : https://en.bitcoin.it/wiki/OP_CHECKSIG
