That is actually a closure for `keyForDisable` .
The reason this logic is in the job (and not in the table) is because `ConceptTimeValuesTable` is not a `ColumnConfigurator`, so it doesn't have an instance of `UserParameters` and methods to retrieve the parameter values. We could put this logic inside the `ConceptTimeValuesTable`, but would require a lot more rework, and at the same time the component would be more complex and difficult to test (as you well said before about writing the file). Passing a closure<Boolean> makes it easier to test this component.
