HarmonyOS 鸿蒙Next Tabs如何将TabContent不均匀分布

可以参考我的代码，左右四栏设置宽度占比18%，中间构造异性导航宽度占比28%

// 异形状态栏
@Component
export struct CusTab2 {
  @State tabArray: Array<number> = [0, 1, 2, 3, 4]
  @State focusIndex: number = 0
  @State pre: number = 0
  @State index: number = 0
  private controller: TabsController = new TabsController()
  @State test: boolean = false
  @State icon: string = 'app.media.icon'

  @Builder Tab(tabName: string, tabItem: number, tabIndex: number) {
    Column({ space: 10 }) {
      Stack() {
        Column() {
          Image($r('app.media.startIcon'))
            .width(32).height(32)
          Text(tabName).fontSize(14)
            .margin({ top: 5 })
        }
        .width('100%')
        .justifyContent(FlexAlign.Center)
      }

      .margin({ bottom: tabIndex === 2 ? 40 : 0 })
    }
    .justifyContent(FlexAlign.Center)
    .onClick(() => {
      this.controller.changeIndex(tabIndex)
      this.focusIndex = tabIndex
    })
    .width(tabIndex === 2 ? '28%' : '18%')
    .padding({ top: 10, bottom: 10 })
    .backgroundColor(Color.White)
    .borderRadius(tabIndex === 2 ? { topLeft: '50%', topRight: '50%' } : {})
  }

  build() {
    Column() {
      Stack({ alignContent: Alignment.BottomStart }) {
        //tabs
        Tabs({ barPosition: BarPosition.End, controller: this.controller }) {
          ForEach(this.tabArray, (item: number, index: number) {
            TabContent() {
              Text('我是页面 ' + item + " 的内容")
                .height(10)
                .width('100%')
                .fontSize(30)
            }
            .backgroundColor(Color.Gray)
          })
        }
        .barHeight(0)
        .animationDuration(100)
        .onChange((index: number) => {
          console.log('foo change')
          this.focusIndex = index
        })

        // 页签
        Row() {
          ForEach(this.tabArray, (item: number, index: number) {
            this.Tab("页签 " + item, item, index)
          })
        }
        .justifyContent(FlexAlign.SpaceBetween)
        .alignItems(VerticalAlign.Bottom)
        .width('100%')
      }
      .width('100%')
    }
    .height('100%')
  }
}

效果如下图所示：
