嵌套ForEach不能自动适应高度

@Entry 
@Component 
struct objList { 
  private scrollerForScroll: Scroller = new Scroller() 
 
  build() { 
    Column() { 
      Text('我是标题') 
        .height(50) 
        .width('100%') 
      Scroll(this.scrollerForScroll) { 
        Column() { 
          ForEach([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 18, 19, 20, 21, 22, 23, 24, 26, 28, 29, 30, 31], (item) => { 
            Row() { 
              Text(item.toString()).margin({ left: 8 }) 
 
            }.width('100%').height(48).padding({ left: 6.5, right: 2.5 }) 
          }, (item: string) => item.toString()) 
        } 
        .padding({ left: 12, right: 12 }) 
        .backgroundColor(Color.White) 
        .borderRadius(8) 
      }.layoutWeight(1) 
    } 
 
  }
