Tabs组件tabbar只能整体相对tabcontent尺寸居中，能否设置偏向一边

@Entry  
@Component  
struct TabsPage {  
  @State tabArray: Array<string> = ['首页', '推荐', '发现', '我的']  
  @State focusIndex: number = 0  
  private controller: TabsController = new TabsController()  
  
  build() {  
    Row() {  
      // 页签 tab bar  
      Column({ space: 5 }) {  
        ForEach(this.tabArray, (item: string, index: number) => {  
          Text(item)  
            .fontSize(18)  
            .fontColor(this.focusIndex === index ? '#007dff' : Color.Black)  
            .height(60)  
            .textAlign(TextAlign.Center)  
            .onClick(() => {  
              this.controller.changeIndex(index)  
              this.focusIndex = index  
            })

      }  
      .width('15%')
