This skill builds on @tanstack/table-core#core and @tanstack/table-core#table-features.

Setup

import Alpine from 'alpinejs'
import {
  FlexRender,
  createTable,
  tableFeatures,
  type ColumnDef,
} from '@tanstack/alpine-table'

type Person = { id: string; name: string }
const features = tableFeatures({})
const columns: Array<ColumnDef<typeof features, Person>> = [
  { accessorKey: 'name', header: 'Name' },
]

Alpine.data('peopleTable', () => {
  const local = Alpine.reactive({
    data: [{ id: '1', name: 'Ada' }] as Array<Person>,
  })
  const table = createTable({
    features,
    columns,
    get data() {
      return local.data
    },
    getRowId: (row) => row.id,
  })

  return { table, FlexRender }
})

window.Alpine = Alpine
Alpine.start()

Render real table structure with x-for; use x-html="FlexRender({ header })" or x-html="FlexRender({ cell })" only for renderer output.

Core Patterns

Pass live options through getters

Wrap changing data in an Alpine.reactive({ data }) object and read local.data through get data(). The property read gives the adapter's effect a dependency to track before it calls table.setOptions.

Read table APIs directly in bindings

The adapter returns a reactive proxy. Expressions such as x-text="table.getRowModel().rows.length" update without a Subscribe component.

Render interaction controls as real markup

Buttons, inputs, and directives belong in the template. Renderer strings are useful for cell content, but x-html does not initialize Alpine directives inside the injected HTML.

Common Mistakes

HIGH Passing a data snapshot

Wrong: createTable({ features, columns, data: local.data }) when local.data will be replaced.

Correct: expose get data() { return local.data }.

The adapter tracks option getters; a captured array does not follow later replacements.

HIGH Interactive directives hidden in x-html

Wrong: return '<button @click="remove()">Remove</button>' from a cell renderer.

Correct: render the button as real template markup and bind the row action there, or use an Alpine.bind bundle.

Alpine does not initialize directives inside content inserted by x-html.

HIGH Expecting Table styling

Wrong: enable sizing or pinning and assume widths/sticky positioning appear.

Correct: apply widths, logical offsets, overflow, and sticky CSS in the Alpine template.

Table exposes state and geometry; it does not own the renderer.
