Albert Barnes Commentary 2 Chronicles 4:19

"And Solomon made all the vessels that were in the house of God, the golden altar also, and the tables whereon was the showbread;" — 2 Chronicles 4:19 (ASV)

The tables - Only a single table is mentioned in 1 Kings 7:48 and 2 Chronicles 29:18. It is supposed that Solomon made ten similar tables, any of which could be used for the showbread, but the bread was never placed on more than one table at a time.
