I'm trying to make a 2D scrollable table. For that I created this layout.
Copy code
Column(modifier = modifier.background(Magenta20)) {
    val scrollState = rememberLazyListState(0)

    val widths = playerState.showColumns.map {
        <http://40.mu|40.mu>
    }
    val rowColors = listOf(White, Gray10)

    LazyRow(state = scrollState, modifier = Modifier.weight(1F).fillMaxWidth().background(Orange20)) {
        item {
            Column(
                modifier = Modifier.background(Green20).fillParentMaxWidth()
            ) {
                Row(modifier = Modifier.fillMaxWidth().background(Yellow20)) {
                    for (column in playerState.showColumns.indices) {
                        Text(
                            playerState.showColumns[column],
                            style = LocalTextStyle.current.copy(fontWeight = FontWeight.Bold),
                            modifier = Modifier.width(widths[column])
                        )
                    }
                }
                LazyColumn(modifier = Modifier.weight(1F).fillMaxWidth().background(Magenta70)) {
                    items(20) {
                        Row(modifier = Modifier.fillParentMaxWidth().background(color = rowColors[it % 2])) {
                            for (column in playerState.showColumns.indices) {
                                Text(
                                    "Value of column $it",
                                    modifier = Modifier.width(widths[column])
                                )
                            }
                        }
                    }
                }
            }
        }
    }
    val scrollbarAdapter = ScrollbarAdapter(scrollState)
    HorizontalScrollbar(adapter = scrollbarAdapter)
}
The main Idea is to have a lazy row to make my content scrollable horizontally. Inside a column that contains the header and a lazy column that contains every row of data. I want my rows to be at least as wide as the screen but grow bigger if they need to. If I remove
fillParentMaxWidth
from the first column my container won't expand to the entire screen. However, if I leave it, the content will shrink to match the current window width. I need the content to be as wide as it needs and at least as wide as the window. Does anyone have a solution to this?
