HarmonyOS list divider中startmargin前面的颜色怎么和listitem保持一致

目前使用list的divider属性并不能满足你想实现的效果，可以自定义实现分隔线效果，参考如下代码：

build() {

  Row(){
    List(){
      ListItem(){
        Flex({direction:FlexDirection.Column,justifyContent:FlexAlign.SpaceBetween}){
          Text('test')
          Divider()
            .color(Color.Red)
              // .height(15)
            .strokeWidth(5)
            .margin({left:50})
        }
      }.backgroundColor(Color.Blue)
      .height(100)
      ListItem(){
        Flex({direction:FlexDirection.Column,justifyContent:FlexAlign.SpaceBetween}){
          Text('test')
          Divider()
            .color(Color.Red)
            .strokeWidth(5)
            .margin({left:50,bottom:0})
        }


      }.backgroundColor(Color.Orange)
      .height(100)
      ListItem(){
        Flex({direction:FlexDirection.Column,justifyContent:FlexAlign.SpaceBetween}){
          Text('test')
          Divider()
            .color(Color.Red)
            .strokeWidth(5)
            .margin({left:50})
        }


      }.backgroundColor(Color.Yellow)
      .height(100)
    }

    // .divider({strokeWidth:5,color:Color.Red,startMargin:50})
    .width('100%').height('100%')
    .backgroundColor(Color.Gray)
  }
}
