migrate-v8-to-v9

# Vue v8-to-v9 migration checklist Before starting, run `intent load @tanstack/table-core#migrate-v8-to-v9`. Audit its entire shared checklist and read the detailed core mappings for APIs present in the application. This checklist adds the Vue-specific changes. Framework prerequisite: Vue 3.2 or newer (`vue >=3.2`). ## Adapter audit - [ ] Replace `useVueTable` with `useTable` and preserve ref/computed/getter inputs. - [ ] Keep features and columns stable, configure explicit features/row-model slots, and complete the shared core checklist. - [ ] Replace `getState()` with tracked atom reads or intentional whole-store reads. Use `computed` for derived template values. - [ ] Pair controlled reactive values with callbacks that resolve both updater forms, or supply stable Vue Store atoms. Remove global `onStateChange`. - [ ] Replace deprecated `table.Subscribe` calls with native reactive reads. Use a child component when you need to preserve a separate component render boundary. - [ ] Adopt FlexRender cell/header/footer shorthand; the old render/props shape remains supported. - [ ] Use `tableOptions` or `createTableHook` only for repeated conventions and explicit context-hook export types when needed to break circular inference. ## Load the affected details When the audit finds old Vue construction, state, rendering, or app-hook code, read [adapter migration details](references/adapter-migration.md) before editing it. For a replacement render scaffold, read [getting started](../getting-started/SKILL.md). For controlled or stale state after migration, read [table state](../table-state/SKILL.md). Shared pinning, sizing, sorting, selection, prototype-method, type, and registry changes stay in the core migration references. Renaming `useVueTable` alone does not complete the migration. ## Verify the migration - [ ] Type-check against the installed v9 adapter and exercise every enabled client/manual feature flow. - [ ] Verify external state writes, reactive data replacement, and the framework rendering paths changed above. - [ ] Complete the core checklist, including layout and selection behavior when those features are used. - [ ] Replace temporary `stockFeatures` when the target is explicit feature tree-shaking. ## API discovery Inspect `node_modules/@tanstack/vue-table/dist/index.d.ts` and the exported adapter declarations. Use `node_modules/@tanstack/table-core/dist/index.d.ts` for shared APIs.
