How to draw with content side by side in jetpack compose

Question

I am using to drawBehind in my Column. I want to draw side by side. I draw line to specific coordinate and want my Text side of it. I tried this code

@Preview(showBackground = true)
@Composable
fun ItemView() {
    val names = listOf("Captain" to "Vice Captain")
    LazyColumn(modifier = Modifier.fillMaxSize()) {
        itemsIndexed(names) { index, item ->

            var titleCoordinates by remember { mutableStateOf<LayoutCoordinates?>(null) }
            Column(
                modifier = Modifier
                    .fillMaxWidth()
                    .drawBehind {
                        val titleBounds = titleCoordinates?.boundsInParent()
                        if (titleBounds != null) {
                            val offset = Offset(x = center.x / 2, y = titleBounds.top)
                            drawLine(
                                color = Color.Black,
                                start = offset,
                                end = offset.copy(y = size.height),
                                strokeWidth = 2.dp.toPx(),
                            )
                        }
                    }
            ) {
                Box(
                    Modifier
                        .padding(top = 24.dp)
                        .onGloballyPositioned { titleCoordinates = it }
                ) {
                    Text(text = item.first, color = Color.Red)
                }
                Text(text = item.second, color = Color.Blue)
            }
        }
    }
}

Actual Output

I can add padding(start = 120.dp) in Column to get my below output. I want to avoid these padding. Is it possible to achieve below output?

Expected Output

Many Thanks

If you you wish to align drawing with actual Content of a Composable you can use Modifier.drawWithContent{}. drawContent() draws what's inside the Composable that this modifier is assigned to while you can position content and drawing based on each other or other requirements.

@Preview
@Composable
fun ItemView() {
    Column(
        modifier = Modifier
            .fillMaxWidth()
            .padding(20.dp)

    ) {
        val names = listOf("Captain" to "Vice Captain")
        LazyColumn(modifier = Modifier.fillMaxSize().border(2.dp, Color.Green)) {
            itemsIndexed(names) { index, item ->

                Column(
                    modifier = Modifier
                        .padding(top = 24.dp)
                        .fillMaxWidth()
                        .drawWithContent {

                            translate(
                                left= 120.dp.toPx(), top = 0f
                            ){
                                drawLine(
                                    color = Color.Black,
                                    start = Offset(0f,0f),
                                    end = Offset(0f, size.height),
                                    strokeWidth = 2.dp.toPx(),
                                )

                                translate(
                                    left= 10.dp.toPx(), top = 0f
                                ){

                                }

                            }
                        }


                ) {
                    Text(text = item.first, color = Color.Red)
                    Text(text = item.second, color = Color.Blue)
                }
            }
        }
    }
