HarmonyOS 鸿蒙Next：动态添加TabContent，样式各异且数量不定

//组件数组
componentList: WrappedBuilder<[]>[] = [wrapBuilder(MyBuilder)];

build() {
  Tabs({ barPosition: BarPosition.Start, index: this.currentIndex, controller: this.tabController }) {
    ForEach(this.componentList, (item: WrappedBuilder<[]>,index: number) => {
      TabContent() {
        item
      }.tabBar(this.tabBuilder(index))
    }, (item: WrappedBuilder<[]>) => JSON.stringify(item))
  }
  .vertical(false)
  .barMode(BarMode.Fixed)
  .barWidth(this.tabBarWidth)
  .barHeight(this.tabBarHeight)
  .animationDuration(this.durationTime)
  .onChange((index: number) => {
      this.currentIndex = index;
  })
}

需要传递什么样的数组给自定义组件才能实现这种功能啊？我是这么做的，根本不行，没法传递组件数组
