HarmonyOS 关于Tabs只能居中的问题

Tabs组件未提供居左的样式，可以用Flex自定义一个靠左的tabBar组件，在onclick事件中通过修改索引值和Tabs组件的索引联动，实现切换效果

@Entry
@Component
struct Index {
  private tabsController: TabsController = new TabsController()
  @State currentIndex: number = 0;

  @Builder
  TabBarBuilder(title: string, targetIndex: number) {
    Text(title)
      .fontWeight(targetIndex === this.currentIndex ? FontWeight.Bold : FontWeight.Normal)
      .margin({ left: 10, right: 10 })
      .onClick(() => {
        this.tabsController.changeIndex(targetIndex)
      })
  }

  build() {
    Row() {
      Column() {
         
Flex({ direction: FlexDirection.Row }) {
        Flex({ direction: FlexDirection.RowReverse }) {
          this.TabBarBuilder('页签1', 0)
          this.TabBarBuilder('页签2', 1)
          this.TabBarBuilder('页签3', 2)
        }

        Tabs({ barPosition: BarPosition.End, controller: this.tabsController }) {
          TabContent() {
            Text("页签1页面")
          }

          TabContent() {
            Text("页签2页面")
          }

          TabContent() {
            Text("页签3页面")
          }
        }.onChange((index: number) => {
          this.currentIndex = index;
        })
      }
    }
  }
}
