[Feature Request] Async Table Column Formatter

### Existing Component
Yes

### Component Name
Table

### Description
Hello. The problem I'm facing is that the formatter of Table Column is sync. And at the moment, I have a API call that send the id of the data i'm working and then I get the name of it and use the name as the value of the format but I do not return anything, it's async. It is possible to implement an callback in table column formatter?
