# Living table A React component in [Beamline](https://beamline.io/)'s [Data & tables](https://beamline.io/components/data) category. Live demo: https://beamline.io/components/living-table A table that shows as much as fits on both axes: width decides which columns show (the rest ride in the name line, moving there rather than vanishing) and zoom decides how much each record shows — every record as one tile with a lens and an honest legend, a row, or a tall row with its history — anchored on the record under the pointer. ## Use it for - The list a team lives in all day ([invoices](https://beamline.io/components/invoices), deals, patients, work orders, runs) where people need both the rows and the whole list at once to find the ones in trouble. - The host gives the columns with their room, priority and fold kind, and the overview's bands as tests; the part never invents a value. ## Not for - Spreadsheet-like editing, virtual scrolling over a server source, column resizing → [data-grid](https://beamline.io/components/data-grid). - A short list with a few columns that always fit → table. ## Anatomy - toolbar: the list's name, its count and sort, the zoom hint and the level control (Overview · Rows · Detail) - rows: a sticky header with sort buttons, rows whose first cell is the name with folded values riding under it, a sticky footer with each aggregate and its scope - detail: each row grown with the columns that left (label and value) and the host's detail - overview: every record as a tile in sort order, sized to fit; the lens over the hovered or focused tile; the legend with the colour's meaning, each band's count as a spotlight toggle, not-loaded count ## States - overview - rows - detail - loading (the level's shape, hatched) - empty - partial (n loaded of m: footer and legend say so, the rest outlined) - changed (a record flashes once; its tile cross-fades) ## Keyboard - + and − (or the level control) zoom, anchored on the focused record, and focus stays on it; Ctrl/⌘ with +, − or the wheel is always the browser's page zoom - In the overview: arrows move between tiles (the lens follows), Home/End to the row's ends, Ctrl+Home/End to the first and last; Enter or Space zooms into Rows on that record and focuses it - In rows: Tab reaches one row (the last one focused); ↑/↓, Home and End move between rows; the headers' sort buttons sort ## Motion A fold that changes moves the values between their cell and the name line (only a fold change travels; a resize that crosses no step places). Zooming keeps the anchor record in place: into the overview its tile lands where its row was, out of it the row grows from its tile, and the others fade in by distance. A changed record flashes once; its tile cross-fades. Reduced motion places at once and still keeps the anchor. ## Props | Prop | Type | Default | Description | | --- | --- | --- | --- | | `label` (required) | `string` | — | The list's name: "Invoices". | | `rows` (required) | `T[]` | — | | | `getRowId` (required) | `(row: T) => string` | — | | | `columns` (required) | `LivingColumn[]` | — | The first column is the name. | | `overview` (required) | `LivingOverview` | — | | | `matching` | `number` | — | How many records match when only some are loaded (`rows` are the loaded ones): the footer and the legend say so, and the overview outlines the rest. | | `noun` | `{ one: string; other: string; }` | — | The record's noun for the counts, by number: `{ one: "invoice", other: "invoices" }`. | | `detail` | `((row: T) => ReactNode)` | — | What a row adds at Detail under the columns that left: its history, its last note. | | `level` | `LivingLevel` | — | | | `defaultLevel` | `LivingLevel` | — | | | `onLevelChange` | `((level: LivingLevel) => void)` | — | | | `sort` | `LivingSort` | — | | | `defaultSort` | `LivingSort` | — | | | `onSortChange` | `((sort: LivingSort) => void)` | — | | | `loading` | `boolean` | — | | | `height` | `number` | — | The table's height in pixels; the overview sizes its tiles so every record fits in it. Default 520. | | `className` | `string` | — | Classes on the documented visual root; no override by default. | | `classNames` | `Partial` | — | Receives the documented native target or imperative handle; omitted by default. | | `defaultLens` | `string` | — | A record read through the overview's lens as it opens, before anyone points (its row id): the lens shows it over its tile without taking focus; pointing anywhere moves it. | ## Built from - [Label](https://beamline.io/components/label.md) - [Segmented control](https://beamline.io/components/segmented-control.md) - [Select](https://beamline.io/components/select.md) - [Spinner](https://beamline.io/components/spinner.md) - [Text morph](https://beamline.io/components/text-morph.md) - [Tooltip](https://beamline.io/components/tooltip.md) ## Dependencies `lucide-react` ## Import ```tsx import { LivingTable } from "@beamline/living-table"; ``` ## Get it Living table is part of Beamline UI.
