@Component  
export struct ColumnNestedScrollPage {  
  build() {  
    Column() {  
      Stack({ alignContent: Alignment.Bottom }) {  
        Scroll() {  
        }  
        .width("100%")  
        .height(1533)  
        .backgroundColor(Color.Orange)  
        .margin({ bottom: -35 })  
        .scrollBar(BarState.On)  
        Button("测试")  
          .width("100%")  
          .height(35)
