HarmonyOS Tabs组件左对齐

当前无法设置左对齐，当前可参考如下代码实现

@Entry
@Component
struct TabDemo5 {
  @State tabArray: Array<number> = [0, 1, 2 ]
  @State focusIndex: number = 0
  @State pre: number = 0
  @State index: number = 0
  private controller: TabsController = new TabsController()
  @State test: boolean = false
  // 单独的页签
  @Builder
  Tab(tabName: string, tabItem: number, tabIndex: number) {
    Column({ space: 20 }) {
      Text(tabName)
        .fontSize(22)
        .fontColor(tabIndex === this.focusIndex ? "#0000FF " : "#000000")
        .margin({top: '17%'})
    }
    .width(85)
    .height(60)
    .onClick(() => {
      this.controller.changeIndex(tabIndex)
      this.focusIndex = tabIndex
    })
  }
  build() {
    Column() {
      Column() {
        // 页签
        Row({ space: 7 }) {
          Scroll() {
            Row() {
              ForEach(this.tabArray, (item: number, index: number) => {
                this.Tab("签页" + item, item, index)
              })
            }
          }
          .align(Alignment.Start)
          .scrollable(ScrollDirection.Horizontal)
          .scrollBar(BarState.Off)
          .width('100%')
          .height('10%')
          .backgroundColor(Color.Pink)
        }
        .width('100%')
        .backgroundColor(Color.Pink)
        //tabs
        Tabs({ barPosition: BarPosition.Start, controller: this.controller }) {
          ForEach(this.tabArray, (item: number, index: number) => {
            TabContent() {
              Text('我是页面 ' + item + " 的内容")
                .height(300)
                .width('100%')
                .fontSize(30)
            }
            .backgroundColor(Color.Gray)
          })
        }
        .barHeight(0)
        .animationDuration(100)
        .onChange((index: number) => {
          console.log('foo change')
          this.focusIndex = index
        })
      }
      .alignItems(HorizontalAlign.Start)
      .width('100%')
    }
    .height('100%')
  }
}
