@Entry  
@Component  
export struct GridTestPage{  
  private days:number[] = [1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0,1,2,3,4,5,6,7,8,9,0]  
  
  build() {  
    List(){  
      ListItem(){  
  
        Grid(){  
          ForEach(this.days,(day:number,index)=>{  
            GridItem(){  
              Row(){  
                Text(day.toString())  
              }  
              .width("100%").height("100%")  
              .justifyContent(FlexAlign.Center)  
              .alignItems(VerticalAlign.Center)  
              .backgroundColor(Color.Red)  
            }  
            .height(56)  
          })  
        }.columnsTemplate('1fr 1fr 1fr 1fr 1fr 1fr 1fr')  
        .scrollBar(BarState.Off)  
        .rowsGap(0)  
        .columnsGap(0)  
        .width('100%')  
  
      }.height(56*Math.ceil(this.days.length/7)).width("100%")  
    }.width("100%").height(392)  
    .listDirection(Axis.Vertical)  
    .padding({left:16,right:16})  
  }
