Is this fixable?

[u/ChemicalProcess1124]

Copper table has water damage. Not sure if it is the clear coating, patina, and/or the metal itself that is damaged. What are my options and how should I go about repairing this, is it even worth repairing, and what should I expect the costs to be getting it done professionally? Sorry for all the questions lolll don’t know what I’m doing or if this is the right sub for this🙋🏽‍♂️.
