table-state

Load `intent load @tanstack/table-core#table-state` first for shared ownership, initialization, updater, and reset rules. Glimmer tracks Table APIs, atom reads, and store-property reads inside template-consumed getters. A value cached outside tracked consumption is only a snapshot. There is no `table.Subscribe` or selector argument to `useTable`; `table.store.subscribe` is intentionally a no-op and cannot drive rendering. ## Controlled tracked setup ```gts import Component from '@glimmer/component' import { tracked } from '@glimmer/tracking' import { on } from '@ember/modifier' import { rowPaginationFeature, tableFeatures, useTable, type PaginationState, } from '@tanstack/ember-table' const features = tableFeatures({ rowPaginationFeature }) const columns = [{ accessorKey: 'name' }] const data = [{ name: 'Ada' }] export default class PageStatus extends Component { @tracked pagination: PaginationState = { pageIndex: 0, pageSize: 10 } table = useTable(this, () => ({ features, columns, data, state: { pagination: this.pagination }, onPaginationChange: (next) => { this.pagination = typeof next === 'function' ? next(this.pagination) : next }, })) get pageNumber() { return this.table.atoms.pagination.get().pageIndex + 1 } nextPage = () => this.table.nextPage() <template> <button type='button' {{on 'click' this.nextPage}}>Page {{this.pageNumber}}</button> </template> } ``` ## Reactive boundaries - Read tracked values inside the options thunk and assign callback results back to their tracked owner. Mutating `this.pagination.pageIndex++` does not notify the thunk. - `features` and `atoms` are construction-time inputs. Updating ordinary live options does not replace the feature set or atom owners; create them once before `useTable`. - Pass the component as the owner for lifecycle cleanup when external atoms are used. The standalone one-argument thunk form remains supported. - Use the adapter's `createAtom` for external Glimmer-reactive ownership. Read it in a tracked getter and use feature APIs or the external atom to write. - Keep features, columns, and data stable. Call receiver-dependent methods through getters or helpers rather than passing extracted methods to templates. ## Read for the task For advanced reactive boundaries, shared atoms, or detailed subscription examples, read [reactivity](references/reactivity.md). For construction or rendering setup, read [getting-started](../getting-started/SKILL.md). ## API discovery Inspect `node_modules/@tanstack/ember-table/declarations/index.d.ts`, `use-table.d.ts`, `signal.d.ts`, and `FlexRender.d.ts`. Core feature APIs are in `node_modules/@tanstack/table-core/dist/features/`.
