HarmonyOS 如何实现vue中v-if的写法

请参考以下示例：

@Entry
@Component
struct ActionSheetExample {
  @State billStatus:number = 1
  @State billStatusDesc:string = ''
  aboutToAppear(): void {
    if (this.billStatus == 0){
      this.billStatusDesc = '等待支付'
    }else  if(this.billStatus == 0){
      this.billStatusDesc ='待预约'
    }else {
      this.billStatusDesc ='待体检'
    }
  }
  build() {
    Column(){
      //实现方式1
      Row(){
        if (this.billStatus == 0){
          Text('等待支付')
        }else  if(this.billStatus == 0){
          Text('待预约')
        }else {
          Text('待体检')
        }
      }
      Divider().width('100%')
        .height(2)
        .backgroundColor(Color.Orange)
      //实现方式2
      Row(){
        Text(this.billStatusDesc)
      }

    }
  }
}
