Please implement "adaptable" feature for validator, same as editor and formatter.

[SimonCVenex]

I love Tabulator's "adaptable" functionality I can use for editor and formatter, but it is missing for validators.

I would like to be able to specify the formatter as "adaptable" in the same way as the editor and formatter.

(if this is already possible, it isn't described in the documentation)

In the meanwhile, I'll be writing a custom validator function to do the job, but I'd prefer to stick to built-in functionality for this, especially as it already works so well with editor and formatter.

I'm using Tabulator 6.3.1.
