HarmonyOS Grid实现滑动时无法修改 layoutDirection 属性

可以通过 Scroll和 Grid嵌套来实现，参考demo如下：

@Entry
@Component
struct GridExample {
  @State numbers: string[] = []

  aboutToAppear() {
    for (let i = 1; i <= 200; i++) {
      this.numbers.push(i + '')
    }
  }

  build() {
    Scroll() {
      Column({ space: 5 }) {
        Grid() {
          ForEach(this.numbers, (day: string) => {
            GridItem() {
              Text(day).fontSize(16).backgroundColor(0xF9CF93)
            }.width(40).height(80).borderWidth(2).borderColor(Color.Red)
          }, (day: string) => day)
        }
        .columnsGap(10)
        .rowsGap(10)
        .backgroundColor(0xFAEEE0)
        .layoutDirection(GridDirection.Row)
      }
      .width('90%').margin({ top: 5, left: 5, right: 5, bottom: 5 })

    }.width("100%")
    .height("100%")
  }
}
