Set section header padding of tableview for second header in old iOS

Question

I'm setting header padding for my tableview in iOS older than 15 explicitly. This works for the top first header (section 1 of tableview), but doesn't work for second header (section 2 of tableview). How could I set it for the second also? Is there something like tableView.tableHeaderView[2] or tableView.tableHeaderView.second ? In code its the place with commented-out places.

func tableView(_ tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
        if tableView.tag == 2 {
            if section == 0 {
                if self.tableView(tableView, numberOfRowsInSection: section) > 0 {
                    let view = UIView()
                    
                    let imageView = UIImageView(image: UIImage(named: "Logo_face"))
                    if #unavailable(iOS 15.0) {
                        imageView.frame = CGRect(x: 10, y: 20, width: 25, height: 25)
                    } else {
                        imageView.frame = CGRect(x: 10, y: 0, width: 25, height: 25)
                    }
                    
                    view.addSubview(imageView)
                    let label = UILabel()
                    label.text = "店舗"
                    label.frame = CGRect(x: 40, y: 0, width: 200, height: 25)
                    view.addSubview(label)
                    if #unavailable(iOS 15.0) { //setting here; works
                        let padding: CGFloat = 20
                        view.frame = CGRect(x: view.frame.origin.x - padding,
                                                  y: view.frame.origin.y - padding,
                                                  width: view.frame.width + 2 * padding,
                                                  height: view.frame.height + 2 * padding)

                        tableView.tableHeaderView = view // this is good
                        label.frame = CGRect(x: 40, y: 20, width: 200, height: 25)
                    }
                    return view
                }
            } else {
                if self.tableView(tableView, numberOfRowsInSection: section) > 0 {
