Update for macOS 12+ (Monterey)

In macOS Monterey, NSTableView can now be wrapped with Table. In addition, Table can support TableColumns with key paths and trailing closures.

struct ContentView: View {
  @State private var characters = StoryCharacter.previewData

  var body: some View {
    Table(characters) {
      TableColumn("🛠") { CharacterIcon($0) }
        .width(20)
      TableColumn("Villain") { Text($0.isVillain ? "Villain" : "Hero") }
        .width(40)
      TableColumn("Name", value: \.name)
      TableColumn("Powers", value: \.powers)
    }
  }
}
