HarmonyOS 多行文本末尾带标签时的缩进

现在存在多行文本，maxLines为2，文本末尾携带一个标签，遮盖标签一直存在，当文本末尾的文字即将到达标签区域时，直接剪切掉，类似于图片的样式，有什么实现方案么

请参考demo：

//Index.ets
import measure from '@ohos.measure';
import { Tags } from './Tags';

function computeTextIndent(text:string):string{
  const sizeOptions:SizeOptions = measure.measureTextSize({
    textContent: text,
    fontSize: '10px'
  });
  let width = sizeOptions.width;
  if(typeof width === 'string'){
    return width.slice(0,width.length-2) + 10 + 'vp';
  }
  if(typeof width === 'number'){
    return width + 10 + 'vp';
  }
  return 0 + 'vp';
}

@Entry
@Component
struct Index {

  @Builder OverlayNode() {
    Column() {
      Tags({ tagsText: '新品新品', tagsType: 'newProduct' })
    }
  }

  build() {
    Column() {
      Row() {
        Text('这里是标题这里是标题这里是标题这里是标题这里是标题这里是标题这里是标题')
          .maxLines(2)
          .textOverflow({ overflow: TextOverflow.Ellipsis })
          .overlay(this.OverlayNode(), {
            offset: { x: 150, y: 20 } })
      }
      .height('100%')
