Validations on Table View fields

Hi ALL, We want to provide Mandatory fields/validations on 3 fields in table view. Initially when the view is loaded they should be highlighted with RED mark indicating them Mandatory and if the users presses enter with empty values, it should give message in application log.

Also this table view is in the guided activity page. So if the user clicks on the Next button in the Roadmap view, the validation in the loaded view should take place and restrict the user to navigate to Next screen with message in application log.

Thanks
