HarmonyOS 如何实现Tabs组件的左侧tabBar靠上对齐

目前原生的tabbar暂时无法实现，可参考示例如下：

import { TabContentComp } from './component/TabContentComp'

@Entry({ routeName: 'ConsultAdvise' })
@Component
export struct ConsultAdvise {
  @State currentIndex: number = 0
  private tabsController: TabsController = new TabsController()

  @Builder
  tabBarBuilder(title: string, targetIndex: number) {
    Column() {
      Image($r("app.media.startIcon")).width(30).height(30)
      Text(title).fontWeight(targetIndex === this.currentIndex ? FontWeight.Bold : FontWeight.Normal)
    }
    .margin({ left: 10, right: 10 })
    .onClick(() => {
      this.tabsController.changeIndex(targetIndex)
    })
  }

  build() {
    Row() {
      Flex({ direction: FlexDirection.Column }) {
        this.tabBarBuilder('热点事件', 0)
        this.tabBarBuilder('推荐视频', 1)
        this.tabBarBuilder('社会生活', 2)
      }
      
      Tabs({ barPosition: BarPosition.Start, controller: this.tabsController }) {
        TabContent() {
          TabContentComp()
        }

        TabContent() {
          TabContentComp()
        }

        TabContent() {
          TabContentComp()
        }
      }
      .vertical(true)
      .barHeight('100%')
      .barBackgroundColor(Color.Black)
      .barWidth(0)
      .scrollable(true)
      .barMode(BarMode.Scrollable)
      .onChange((index: number) => {
        this.currentIndex = index;
      })
    }.backgroundColor('#eee')
    .width('100%').height('100%')
  }
}
