Android 懒惰的垂直网格中盒子的重量Jetpack组合

I am trying to get my Lazy Vertical Grid to be working the way I have it in the non-JetpackCompose version. I have this keypad that contains buttons ranging from 0 to 9 and a clear button. The grid is 3 buttons wide, it starts with 1 to 9, the last column contains 0 and CLEAR, however the CLEAR buttons should be twice as wide as the other buttons. See this image from the non-Jetpack Compose version of my app:

这是我目前拥有的代码，请注意，我刚刚开始从事Jetpack编写工作，所以与其他XML样式相比，我的知识并不是很高.

LazyVerticalGrid(
            GridCells.Fixed(3),
            modifier = Modifier.fillMaxWidth()
        ) {
            itemsIndexed(keypadBtn + listOf("0", "CLEAR")) { _, keyTxt ->
                Box(
                    contentAlignment = Alignment.Center,
                    modifier = Modifier
                        .fillMaxWidth()
                        .size(width = if(keyTxt == "CLEAR") 260.dp else 120.dp, height = 80.dp)
                        .padding(start = 5.dp, end = 5.dp, top = 5.dp, bottom = 5.dp)
                        .clip(RoundedCornerShape(16.dp))
                        .background(if (keyTxt == "CLEAR") Color.Gray else Color.White)
                        .weight(if (keyTxt == "CLEAR") 2f else 1f)
                        .clickable {
                            // Handle click action here
                        }
                ) {
                    Text(
                        text = keyTxt,
                        color = if (keyTxt == "CLEAR") Color.White else Color.Black,
                        fontSize = 36.sp,
                        fontWeight = FontWeight.Bold
                    )
                }
            }
        }
