# Table List

Turns table-style rows and columns into a grouped list of rows with a title, description and trailing values.

Table List is an open-source mobile pattern from suiss/uim: components composed into a flow for React Native and Expo, with SwiftUI and Jetpack Compose versions built from the same design tokens. The @esuiss/uim CLI copies its source into your project, so you own the code.

```tsx

@Composable
fun TableListDefault() {
    Column(verticalArrangement = Arrangement.spacedBy(32.dp)) {
        TableList(
            rows = tableListInvoices,
            columns = tableListColumns,
            getKey = { row, _ -> row.id },
            title = "Invoices",
            onRowClick = {},
        )
        TableList(rows = emptyList(), columns = tableListColumns, emptyText = "No invoices yet.")
    }
}
```

`TableList` takes `rows` and a `columns` definition, and renders each row as a `TableListRow` inside one rounded group. Each column has a `slot` that decides where its cell goes: the row title, the description line, the trailing side, or nowhere.

The row parts are also exported, so you can build the same grouped look inside a `FlatList` for long or virtualized lists.

## Installation

```bash title="Terminal"
npx @esuiss/uim@latest add table-list
```

```bash title="Terminal"
npx @esuiss/uim@latest add table-list --platform swift
```

```bash title="Terminal"
npx @esuiss/uim@latest add table-list --platform kotlin
```

The CLI also adds what it builds on: [Item](/docs/components/item), [Text](/docs/components/text).

### Manual

4. Update the import paths to match your project.

**StyleSheet**

1. Add the pieces it builds on: [Item](/docs/components/item), [Text](/docs/components/text).

2. Copy the source into `components/patterns/table-list.tsx`:

3. Update the import paths to match your project.

**SwiftUI**

1. Target iOS 17 or later.

2. Copy the theme files every view uses:

4. Add the files to your app target.

**Jetpack Compose**

1. Set `minSdk` to 24 or higher and add the dependencies:

```kotlin title="build.gradle.kts"
implementation(platform("androidx.compose:compose-bom:2026.09.00"))
implementation("androidx.compose.foundation:foundation")
implementation("androidx.compose.ui:ui")
implementation("com.adamglin:phosphor-icon-android:1.0.0")
```

2. Copy the theme files every view uses:

4. Update the `com.esuiss.ui` package names to match your project.

## Usage

```tsx
import { TableListTitle, TableListHeader, TableListFooter, TableListSeparator, TableListRow, TableList } from "@/components/patterns/table-list"
```

```tsx
<View className="gap-8">
  <TableList
    title="Invoices"
    rows={invoices}
    columns={columns}
    getKey={(row) => row.id}
    onRowPress={() => {}}
  />
  <TableList rows={[]} columns={columns} emptyText="No invoices yet." />
</View>
```

Define columns with `key`, `header`, `cell` and `slot`. Several `description` columns are joined with ` · `, and several `trailing` columns are shown side by side. Use `mobileCell` to render a different value than `cell` in the list, such as a shorter date.

Pass `onRowPress` to make rows pressable. When there are no rows, `emptyText` is shown in the group. The `TableListColumn` type is exported.

With a `FlatList`, use `TableListRow` as the item, pass `first` and `last` to round the ends, `TableListSeparator` as `ItemSeparatorComponent`, and `TableListHeader` and `TableListFooter` around the list.

## Examples

### With flat list

Builds the grouped list in a `FlatList` with a header, footer and separators.

## API Reference

### TableListTitle

A large heading above the list.

### TableListHeader

A small uppercase heading above a group.

### TableListFooter

A note below a group.

### TableListSeparator

An inset divider between rows.

### TableListRow

### TableList

## Accessibility

- The group has the `list` role; rows have the `listitem` role, or `button` when `onRowPress` is set.
- `TableListTitle` and `TableListHeader` have the `heading` role.
- Separators are hidden from screen readers.

## Notes

- Rows use `bg-surface-secondary` and `bg-surface-tertiary` when pressed.
- The `header` and `align` column fields are not rendered by the list layout.
