This skill builds on @tanstack/table-core#core and @tanstack/table-core#table-features. Read them first for the headless model and explicit features.

Setup

import { Component, signal } from '@angular/core'
import { FlexRender, injectTable, tableFeatures } from '@tanstack/angular-table'

type Person = { name: string; age: number }
const features = tableFeatures({})
const columns = [
  { accessorKey: 'name', header: 'Name' },
  { accessorKey: 'age', header: 'Age' },
]

@Component({
  selector: 'app-table',
  imports: [FlexRender],
  template: `<table>
    <tbody>
      @for (row of table.getRowModel().rows; track row.id) {
        <tr>
          @for (cell of row.getAllCells(); track cell.id) {
            <td>
              <ng-container *flexRenderCell="cell; let value">{{
                value
              }}</ng-container>
            </td>
          }
        </tr>
      }
    </tbody>
  </table>`,
})
export class TableComponent {
  readonly data = signal<Person[]>([{ name: 'Ada', age: 36 }])
  readonly table = injectTable(() => ({ features, columns, data: this.data() }))
}

Core Patterns

Keep static inputs outside the initializer

injectTable reruns its options initializer when a signal read changes. Define features, row-model factories, and columns at module or stable class scope; read only changing values inside.

Render each content kind correctly

Import FlexRender for *flexRender, *flexRenderCell, *flexRenderHeader, and *flexRenderFooter. Definitions may yield primitives, TemplateRef, component types, or flexRenderComponent(...); Table does not supply markup or CSS.

Common Mistakes

CRITICAL Calling injectTable outside DI

Wrong:

export function makeTable() {
  return injectTable(() => ({ features, columns, data }))
}

Correct:

export class TableComponent {
  readonly table = injectTable(() => ({ features, columns, data: this.data() }))
}

injectTable asserts an Angular injection context and registers lifecycle cleanup there.

Source: packages/angular-table/src/injectTable.ts

HIGH Reallocating static options reactively

Wrong:

injectTable(() => ({
  features: tableFeatures({}),
  columns: makeColumns(),
  data: this.data(),
}))

Correct:

const features = tableFeatures({})
const columns = makeColumns()
injectTable(() => ({ features, columns, data: this.data() }))

Every signal change reruns the initializer; rebuilding static inputs invalidates memoized Table work.

Source: packages/angular-table/src/injectTable.ts

HIGH Treating a render function as a component

Wrong:

cell: () => flexRenderComponent(() => 'value')

Correct:

cell: () => 'value'

flexRenderComponent wraps an Angular component type; ordinary functions and primitives are handled directly by FlexRender.

API Discovery

Inspect node_modules/@tanstack/angular-table/dist/types/ for the bundled public API; inspect optional feature APIs in installed @tanstack/table-core/dist/features/.
