I need to make below table like structure in one of the apps I am developing. I am creating this table using UITableView & I need my table column width to change based on the screen orientation. I have set constraints for column width & I will assign values to these using the screen width in my viewDidLoad().

However, I am not able to figure out how to re-align these constraints when screen orientation changes. I figured out that viewWillTransition() will be called when orientation is changed & I recalculated the constraints inside that & called setNeedsLayout() for the table view. However, I am not able to make my table view to reset the table column width when screen orientation is changed. I am new to IOS platform and any help will be greatly appreciated.

override func viewWillTransition(to size: CGSize, with coordinator: UIViewControllerTransitionCoordinator) {
    super.viewWillTransition(to: size, with: coordinator)

    let animationHandler: ((UIViewControllerTransitionCoordinatorContext) -> Void) = { [weak self] (context) in
        // This block will be called several times during rotation,
        // so if you want your tableView change more smooth reload it here too.
        self?.yourTable.reloadData()
    }

    let completionHandler: ((UIViewControllerTransitionCoordinatorContext) -> Void) = { [weak self] (context) in
        // This block will be called when rotation will be completed
        self?.yourTable.reloadData()
    }

    coordinator.animate(alongsideTransition: animationHandler, completion: completionHandler)
