Datatable validation

Webix JS
#1

Is it possible to validate only one cell from a datatable?

I can validate the whole column like this:

       "value": webix.rules.isNumber
}```

But it would be great to validate only "value" of the row with id "only_number".

The validation rule can be defined as a function. Therefore, you can check the item’s id and apply a rule for a particular cell. For example:
