Item을 원하는 비율로 배치하기

//item 한줄에 2개
columns = GridCells.Fixed(2)
//itme 한줄에 128dp씩
columns = GridCells.Adaptive(128.dp)
//custom으로 정의
columns = object: GridCells {
	override fun Density.calculateCrossAxisCellSizes(
      availableSize: Int,
      spacing: Int
    ): List<Int> {
      val firstColumn = (availableSize - spacing) * 2 / 3
      val secondColumn = availableSize - spacing - firstColumn
      return listOf(firstColumn, secondColumn)
    }
 }
