HarmonyOS .divider(this.egDivider) 如何在列表最后一个元素下面也加上一条分割线

可以使用自定义ListItem结合条件渲染，参考代码如下：

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';
  scroller: Scroller = new Scroller()
  @State dataSource: Array<ListItemModel> = new Array()

  aboutToAppear(): void {
    let index = 0;
    while (index < 50) {
      this.dataSource.push({ "title": index.toString(), "showLine": true })
      index++
    }
  }

  build() {
    Column() {
      List({ scroller: this.scroller }) {
        ForEach(this.dataSource, (item: ListItemModel) => {
          ListItem() {
            ListItemView({ item: item })
          }
        }, (item: ListItemModel) => item.title)
      }.scrollBar(BarState.Off)
      .onWillScroll((scrollOffset: number, scrollState: ScrollState) => {
      })
    }
    .backgroundColor('#0D182431')
    .width('100%')
    .height('100%')
  }
}

@Component
struct ListItemView {
  item: ListItemModel = new ListItemModel();

  build() {
    Column() {
      Text("item" + this.item.title)
        .fontSize(16)
        .fontColor(Color.Black)
        .height(80)
        .width("100%")
        .textAlign(TextAlign.Center)
        .backgroundColor(Color.White)
      if (this.item.showLine) {
        Divider().strokeWidth(1).color(Color.Red)
      }
    }
    .width("100%")
    .height(81)
    .borderRadius(10)
    .backgroundColor(Color.White)
    .justifyContent(FlexAlign.SpaceBetween)
  }
}

class ListItemModel {
  constructor() {
  }

  title: string = ""
  showLine: boolean = true
}
