如何在DataElement中控制SegmentedControl的外观

import SwiftUI

struct ContentView: View {
    @State private var selectedSegment = 0
    
    var body: some View {
        VStack {
            Text("Selected segment: \(selectedSegment)")
            
            SegmentedControl(selection: $selectedSegment) {
                Text("Segment 1")
                    .tag(0)
                Text("Segment 2")
                    .tag(1)
                Text("Segment 3")
                    .tag(2)
            }
            .segmentedControlStyle(MySegmentedControlStyle())
        }
    }
}

struct MySegmentedControlStyle: SegmentedControlStyle {
    func makeBody(configuration: Configuration) -> some View {
        HStack {
            ForEach(0..<configuration.segmentCount) { index in
                configuration.label(forSegment: index)
                    .padding()
                    .background(configuration.isSelected(index) ? Color.blue : Color.gray)
                    .foregroundColor(.white)
                    .cornerRadius(10)
            }
        }
        .padding()
    }
}
