I've inspired some of the configurator used to config per page NavigationView nav bar style and write some simple UITableView per page configurator not use UITableView.appearance() global approach

   import SwiftUI

    struct TableViewConfigurator: UIViewControllerRepresentable {

        var configure: (UITableView) -> Void = { _ in }

        func makeUIViewController(context: UIViewControllerRepresentableContext) -> UIViewController {

            UIViewController()
        }

        func updateUIViewController(_ uiViewController: UIViewController, context: UIViewControllerRepresentableContext) {

            let tableViews = uiViewController.navigationController?.topViewController?.view.subviews(ofType: UITableView.self) ?? [UITableView]()

            for tableView in tableViews {
                self.configure(tableView)
            }
        }
    }

Then there is UIView extension needed to find all UITableViews

extension UIView {
    func subviews(ofType WhatType:T.Type) -> [T] {
        var result = self.subviews.compactMap {$0 as? T}
        for sub in self.subviews {
            result.append(contentsOf: sub.subviews(ofType:WhatType))
        }
        return result
    }
}

And usage at the end is:

List {

}.background(TableViewConfigurator {
    $0.backgroundColor = .red
})

Maybe one thing should be improved that is usage of navigationController?.topViewController to make it work even without navigationController in view controllers hierarchy
