@Entry 
@Component 
struct GridExample { 
  @State numbers1: String[] = ['0', '1', '2', '3', '4'] 
  build() { 
    Column({ space: 5 }) { 
      Grid() { 
        ForEach(this.numbers1, (day: string) => { 
          GridItem() { 
            Text(day) 
              .fontSize(16) 
              .backgroundColor(0xF9CF93) 
              .width('100%') 
              .height('100%') 
              .textAlign(TextAlign.Center) 
          } 
        }, (day: string) => day) 
      } 
      .columnsTemplate('repeat(auto-fit, 90)') 
      // .columnsTemplate('repeat(auto-fill, 90)') 
      .rowsTemplate('1fr 1fr 1fr 1fr 1fr')

  }
