HarmonyOS Column布局包含list

@Entry 
@Component 
struct Index { 
  @State strList : Array<String> = ['Hello World','init','1','2','3','4','5','6','7','8','9','10','11','12','13','14','15','16','17'] 
  build() { 
    Column() { 
      Text("111111") 
        .fontSize(100) 
      List() { 
        ForEach(this.strList, (item: string,index: number) => { 
          ListItem(){ 
            Text(item) 
              .fontSize(100) 
          } 
        }) 
      } 
      .layoutWeight(300) 
    } 
    .width('100%') 
    .height('100%')
