HarmonyOS Grid 组件如何根据子元素自适应高度？

参考如下Demo：

@Entry
@Component
struct GridExample {
  @State Number: String[] = ['0', '1', '2', '3', '4','5','6','7','8','9']
  scroller: Scroller = new Scroller()
  build() {
    Column({ space: 5 }) {
      Text('scroll').fontColor(0xCCCCCC).fontSize(9).width('90%')
      Grid(this.scroller) {
        ForEach(this.Number, (day: string) => {
          ForEach(this.Number, (day: string) => {
            GridItem() {
              Text(day)
                .fontSize(16)
                .backgroundColor(0xF9CF93)
                .width('100%')
                .height(80)
                .textAlign(TextAlign.Center)
            }
          }, (day: string) => day)
        }, (day: string) => day)
      }
      .columnsTemplate('1fr 1fr 1fr 1fr 1fr')
      .columnsGap(10)
      .rowsGap(10)
      .onScrollIndex((first: number) => {
        console.info(first.toString())
      })
      .width('80%')
      .layoutDirection(GridDirection.Row)
      .maxCount(3)
      .backgroundColor(0xFAEEE0)
      .scrollBarWidth(0)
    }.width('100%').margin({ top: 5 })
  }
}
 
//在外层布局添加滚动布局scroll
@Entry
@Component
struct GridExample {
  @State Number: String[] = ['0', '1', '2', '3', '4','5','6','7','8','9']
  scroller: Scroller = new Scroller()
  build() {
    Scroll() {
      Column({ space: 5 }) {
        Text('scroll').fontColor(0xCCCCCC).fontSize(9).width('90%')
        Grid(this.scroller) {
          ForEach(this.Number, (day: string) => {
            ForEach(this.Number, (day: string) => {
              GridItem() {
                Text(day)
                  .fontSize(16)
                  .backgroundColor(0xF9CF93)
                  .width('100%')
                  .height(80)
                  .textAlign(TextAlign.Center)
              }
            }, (day: string) => day)
          }, (day: string) => day)
        }
        .columnsTemplate('1fr 1fr 1fr 1fr 1fr')
        .columnsGap(10)
        .rowsGap(10)
        .onScrollIndex((first: number) => {
          console.info(first.toString())
        })
        .width('80%')
        .layoutDirection(GridDirection.Row)
        .maxCount(3)
        .backgroundColor(0xFAEEE0)
        .scrollBarWidth(0)
      }.width('100%').margin({ top: 5 })
    }
    .scrollBarWidth(0)
  }
}
