fix(table): enhance aggregatedCell with bound cellComponents in createAppColumnHelper

[grzdev]

Summary

In createTableHook, AppColumnDefBase and AppDisplayColumnDef enhance cell, header, and footer templates with registered cellComponents and headerComponents via AppCellContext and AppHeaderContext.

However, aggregatedCell (used with aggregation features) was omitted from the enhancement mapping and remained typed against the base unenhanced CellContext. As a result, accessing pre-bound cell components (e.g. cell.NumberCell) was allowed inside cell on a column, but produced a TypeScript error when attempted inside aggregatedCell on that same column.

Changes

• In AppColumnDefBase and AppDisplayColumnDef, omit aggregatedCell alongside cell, header, and footer.
• Add aggregatedCell?: AppColumnDefTemplate<AppCellContext<...>> typed with the bound TCellComponents.
• Apply this across React, Preact, Solid, Svelte, and Vue table adapters.
• Add regression coverage in packages/react-table/tests/createTableHook.test.tsx.
• Add changeset for table adapters.

Summary by CodeRabbit

• Bug Fixes
  • Fixed aggregated table cells across React, Preact, Solid, Svelte, and Vue so they can render with the same configured cell components as regular cells.
• New Features
  • Added support for defining aggregated-cell renderers with the same component-aware context available to regular cell renderers.

📝 Walkthrough

Walkthrough

The five framework table packages now type aggregatedCell with the app-specific cell context, including bound cell components. The React test adds an aggregatedCell renderer, and the changeset records patch releases for all five packages.

Aggregated Cell Context Typing

Layer / File(s)	Summary
Add app-specific aggregated cell types packages/react-table/src/createTableHook.tsx, packages/preact-table/src/createTableHook.tsx, packages/solid-table/src/createTableHook.tsx, packages/svelte-table/src/createTableHook.svelte.ts, packages/vue-table/src/createTableHook.ts, packages/react-table/tests/createTableHook.test.tsx, .changeset/app-column-helper-aggregated-cell.md	Column and display-column definitions in all five framework packages use the enhanced cell context for aggregatedCell. The React test adds an aggregated cell renderer, and the changeset records patch releases for the five packages.

Merge Risk: 🔵 Low · up to dff2a

The typing change appears mergeable with a bounded coverage gap: the new test would not catch a runtime failure when an aggregated cell renders a bound component.

Test checks types only.

The aggregatedCell renderer is added to the column. The test never renders an aggregated (grouped) row, so the runtime branch in FlexRender stays untested. The type-level regression is still covered by the compile step, which is the purpose of this change. Add a render assertion only if you want runtime coverage.

The `aggregatedCell` renderer in the test is only checked at compile time; no
code change is needed because runtime coverage is optional. Keep this change
focused on the type-level regression and do not add a render assertion.
