Lazy Table

Lazy table library for Compose UI.

Lazy table allows to display columns and rows of data on the two directional plane. It is build on the MinaBox (which is build on LazyLayout) and provides methods to register item(s) and handles scrolling on the plane.

Multiplatform

Library supports Android, iOS, Desktop (Windows, MacOS, Linux) and Wasm targets.

Usage

Get a dependency

Step 1. Add the MavenCentral repository to your build file. Add it in your root build.gradle.kts at the end of repositories:

allprojects {
    repositories {
        ...
        mavenCentral()
    }
}

Or in settings.gradle.kts:

dependencyResolutionManagement {
    repositories {
        ...
        mavenCentral()
    }
}

Step 2. Add the dependency. Check latest version on the releases page.

dependencies {
    implementation("io.github.oleksandrbalan:lazytable:$version")
}

Use in Composable

The core element of the LazyTable layout is a content lambda, where items are registered in the similar manner as in LazyColumn or LazyRow. The main difference is that each item must provide its position and size in the layoutInfo lambda. Each item defines its position by specifying the column and row and size by specifying how much columns or rows it occupies (by default is set to 1).

The size of the cells are defined via dimensions parameter. There are multiple lazyTableDimensions methods which creates the dimensions for all or each column / row.

Lazy table also allows to specify how many columns / rows should be pinned and thus be visible when user navigates in the table. Check the pinConfiguration parameter.

It is also possible to observe on the scroll state and change it programmatically using an instance of the LazyTableState.

val columns = 10
val rows = 10
LazyTable(
    dimensions = lazyTableDimensions(48.dp, 32.dp)
) {
    items(
        count = columns * rows,
        layoutInfo = {
            LazyTableItem(
                column = it % columns,
                row = it / columns,
            )
        }
    ) { index ->
        Text(text = "#$index")
    }
}

See Demo application and examples for more usage examples.
