Usage

Basic

Loading demo...

Row Selection

selectable adds a selection column; v-model:selected-keys syncs the selected rows.

Loading demo...

Skeleton Loading

loadingVariant="skeleton" draws placeholder rows while there are none; a refresh of existing rows shows only a bar under the header.

Loading demo...

Expandable Rows

expandable adds a leading toggle column; the #expanded slot renders the detail under a row.

Loading demo...

Records Table

A wide layout with a pinned header and footer, a frozen first column, and selection highlighting; cells compose TxTag, TxDotIndicator, and TxCellLink.

Loading demo...

Data Operations Panel

TxPagination pages the list, and TxSkeleton / TxLayoutSkeleton preview the loading state.

Best Practices

Pass a stable rowKey for business lists; to keep selection across pages, drive selectedKeys with business ids, not default indexes.
For server-loaded lists, use loadingVariant="skeleton" with skeletonRows set to the page size; keep the default overlay for short local waits.
Give fixed columns numeric px width / minWidth, and keep one horizontal scroller: scrollX, or an outer overflow-x: auto.
A pinned header or footer needs maxHeight or a scrolling ancestor; don't nest the table in TxScroll's default mode, whose transform scrolling disables sticky.
Sort on comparable fields such as timestamps or ranks, never on formatted relative-time text.

API Reference

Props

Name	Type	Default	Description
`columns`	`DataTableColumn[]`	`[]`	Column config.
`data`	`any[]`	`[]`	Data source.
`rowKey`	`keyof T \| (row: T, index: number) => string \| number`	`index`	Unique row key.
`loading`	`boolean`	`false`	Loading state.
`loadingVariant`	`'overlay' \| 'skeleton'`	`'overlay'`	`overlay` veils the table with a spinner; `skeleton` draws placeholder rows, or only a bar when rows exist.
`skeletonRows`	`number`	`5`	Placeholder rows before the first data lands; match the page size so nothing moves.
`emptyText`	`string`	`'No data'`	Empty text.
`striped`	`boolean`	`false`	Zebra rows.
`bordered`	`boolean`	`false`	Show borders.
`hover`	`boolean`	`true`	Hover highlight.
`interactiveRows`	`boolean`	`false`	Makes rows focusable so Enter / Space fire `rowClick`; on automatically with a `rowClick` listener.
`selectable`	`boolean`	`false`	Adds a selection column.
`selectedKeys`	`Array<string \| number>`	`[]`	Keys of the selected rows.
`expandable`	`boolean`	`false`	Adds a leading toggle column; an expanded row renders a detail row beneath it.
`defaultExpandedKeys`	`Array<string \| number>`	`[]`	Initial expanded rows when uncontrolled; `expandedKeys` wins if both are passed.
`expandedKeys`	`Array<string \| number>`	-	Controlled expanded rows, bound with `v-model:expanded-keys`.
`rowExpandable`	`(row, index) => boolean`	-	Per-row gate for expanding; a rejected row keeps an empty leading cell.
`expandLabel`	`string`	`'Expand row'`	Accessible name of a closed toggle.
`collapseLabel`	`string`	`'Collapse row'`	Accessible name of an open toggle.
`defaultSort`	`{ key: string; order: 'asc' \| 'desc' \| null }`	`null`	Initial sort when uncontrolled; pass either this or `sort`.
`sort`	`{ key: string; order: 'asc' \| 'desc' \| null } \| null`	-	Controlled sort; `null` means unsorted.
`sortOnClient`	`boolean`	`true`	Sorts locally; set `false` for remote sorting, which only emits.
`sortCycle`	`'tri' \| 'bi'`	`'tri'`	`tri`: ascending → descending → unsorted; `bi` alternates and never unsorts.
`tableLayout`	`'auto' \| 'fixed'`	`'auto'`	Native `table-layout`; use `fixed` when column widths must stay stable.
`nowrap`	`boolean`	`false`	Prevents wrapping in every header and cell.
`maxHeight`	`string \| number`	-	Caps the height and scrolls the table vertically; what sticky rows stick to.
`scrollX`	`boolean`	`false`	Scrolls horizontally inside the component; for wide tables with fixed columns.
`stickyHeader`	`boolean`	`false`	Pins the header row.
`stickyFooter`	`boolean`	`false`	Pins the summary row.
`rowClass`	`(row, index) => string \| string[] \| Record<string, boolean>`	-	Extra classes per row, such as a tint by state.
`highlightSelected`	`boolean`	`false`	Tints selected rows.

Events

Event	Payload	Description
`update:selectedKeys`	`(keys)`	Selection update.
`selectionChange`	`(keys)`	Selection change.
`update:expandedKeys`	`(keys)`	Expansion update; fires in controlled and uncontrolled modes.
`expand`	`({ row, index, expanded })`	A row was expanded or collapsed.
`sortChange`	`(sort)`	Sort change.
`update:sort`	`(sort)`	Sort change; fires in controlled and uncontrolled modes.
`rowClick`	`({ row, index })`	Row click.

Slots

Name	Description
`header-<columnKey>`	Custom header; receives `{ column, sorted, order, toggle }`, where `toggle` advances the sort cycle.
`cell-<columnKey>`	Custom cell; receives `{ row, column, value, index }`.
`expanded`	Detail of an expanded row, spanning every column; receives `{ row, index }`.
`footer`	The whole summary row of your own `<td>`s, which can span columns. Any footer slot renders a `<tfoot>`.
`footer-<columnKey>`	One summary cell per column; receives `{ column, data }`. `footer` wins when both exist.
`empty`	Empty state when there are no rows and `loading=false`.

DataTableColumn

Field	Type	Description
`key`	`string`	Column key.
`title`	`string`	Header title.
`dataIndex`	`string`	Data field.
`width`	`string \| number`	Column width.
`minWidth`	`string \| number`	Minimum column width.
`maxWidth`	`string \| number`	Maximum column width.
`auto`	`boolean`	Forces the column width to `auto`.
`fixed`	`boolean \| 'left' \| 'right'`	Sticky side; `true` means `'left'`. Left offsets already include the toggle and selection columns.
`nowrap`	`boolean`	Prevents wrapping in this column.
`align`	`'left' \| 'center' \| 'right'`	Alignment.
`sortable`	`boolean`	Sortable.
`sorter`	`(a, b) => number`	Custom sorter.
`format`	`(value, row, index) => string`	Cell formatter.
`headerClass`	`string`	Header class.
`cellClass`	`string`	Cell class.

Overview

Passing sort or expandedKeys (even null or []) makes it controlled: the table only emits updates and renders what the parent sends back.
Sortable headers carry scope="col" and aria-sort; click, Enter, and Space step through sortCycle.
On a partial selection the select-all box is indeterminate (aria-checked="mixed"); clicks in the selection and toggle cells never fire rowClick.
loading sets aria-busy on the <table>, and the empty state stays hidden while loading.
Placeholder rows are aria-hidden and as tall as a one-line row; the refresh bar holds still under reduced motion.
stickyHeader, stickyFooter, or maxHeight switches to border-collapse: separate. The last row has no bottom rule; the rule above a tfoot stays.

Technologies

The skeleton variant renders TxSkeleton. The on-demand style plugin loads its sheet; when importing styles by hand, add @talex-touch/tuffex/skeleton/style.css.
