     * row is valid. If the row is valid, simply return ValidationResult.OK.
     * Otherwise, constructs a ValidationResult and provide the id and message.
     * You can also return RowValidationResult which has an array of invalid column indices.
     * Usually when you validate a row, you will be able to figure out values in one or several columns
     * are invalid. You can pass them to RowValidationResult and return it. Listeners for the RowValidator can decide to display
     * some error indications to indicate which cells are invalid.
