  • Annotate every built-in filterFn_*, sortFn_*, and aggregationFn_* with /* @__PURE__ */, and the construct*Fn factories with @__NO_SIDE_EFFECTS__. Importing one fn now bundles only that fn (filterFn_equals: 752 → 168 B brotli; aggregationFn_sum under esbuild: 767 → 176 B).
  • Stop the core and the filtered, sorted, and grouped row models from importing other features' utils. They now go through the internal core/featureStubs.ts, which calls the feature's registered API or falls back to no-feature behavior. A minimal React useTable drops from 8.97 to 8.41 kB, and grouping without rowAggregationFeature no longer bundles the aggregation executor.
  • Add table.autoResetSorting(), rename the Table_RowPagination type member _autoResetPageIndex to autoResetPageIndex (the runtime method never had the underscore), and fix the getOrderColumnsFn memo key, which never matched.
  • Move constructAggregationFn out of rowAggregationFeature.types.ts so .types files stay type-only.
  • Add size-limit guards for constructTable and single-fn imports.
  • Add pnpm size:devtools (scripts/generate-bundle-sizes.mjs), which measures every feature, row model, and built-in fn with size-limit's pipeline. The devtools Features panel shows those sizes, and its total counts shared code once (within ~2% of real bundles on held-out combinations; a plain sum overcounts by up to 40%).

Notes

The _autoResetPageIndex → autoResetPageIndex type rename touches public types. docs/reference still needs pnpm generate-docs.

Summary by CodeRabbit

  • New Features
    • Added autoResetSorting() to reset sorting after data changes when enabled.
    • Devtools now show estimated bundle sizes for registered features, row models, and built-in functions.
  • Improvements
    • Pagination’s page-index reset method is now named autoResetPageIndex().
    • Improved tree-shaking to help reduce bundles when using selected table features and built-in functions.
    • Global filtering now applies only when a filter value, filter function, and eligible columns are available.

📝 Walkthrough

Walkthrough

Table-core changes update optional-feature dispatch, reset APIs, and tree-shaking annotations. Devtools adds a bundle-size measurement and estimation pipeline and uses its results to report sizes in the Features panel.

Changes

Table core and devtools

Layer / File(s) Summary
Shared optional-feature dispatch
packages/table-core/src/core/featureStubs.ts, packages/table-core/src/core/columns/coreColumnsFeature.utils.ts, packages/table-core/src/core/headers/*, packages/table-core/src/core/row-models/createCoreRowModel.ts, packages/table-core/src/features/column-filtering/createFilteredRowModel.ts, packages/table-core/src/features/column-grouping/createGroupedRowModel.ts
Core helpers provide defaults for optional feature APIs. Header and row-model code uses these helpers for visibility, filtering, resets, and aggregation.
Reset APIs and tree-shaking annotations
packages/table-core/src/features/row-expanding/rowExpandingFeature.types.ts, packages/table-core/src/features/row-pagination/rowPaginationFeature.types.ts, packages/table-core/src/features/row-sorting/*, packages/table-core/src/features/column-filtering/filterFns.ts, packages/table-core/src/features/row-aggregation/*, packages/table-core/src/features/cell-spanning/cellSpanningFeature.utils.ts
Sorting adds an auto-reset table method, and pagination renames its reset method. Built-in filter, sort, and aggregation functions receive purity annotations; aggregation executor access moves through the optional-feature stub.
Bundle-size measurement pipeline
package.json, scripts/generate-bundle-sizes.mjs, packages/table-devtools/src/bundleSizes.ts
A script measures table-core bundles, shared declaration chunks, and validation combinations. It writes the generated size catalog and validation fixture; package scripts and limits configure its use.
Bundle-size estimator and validation
packages/table-devtools/src/estimateBundleSize.ts, packages/table-devtools/tests/estimateBundleSize.test.ts, packages/table-devtools/tests/fixtures/bundleSizeValidation.json
The estimator combines selected items’ measurements with shared chunk data and a fitted curve. Tests cover unknown selections, shared chunks, and estimates against measured fixture cases.
Features panel size reporting
packages/table-devtools/src/components/FeaturesPanel.tsx, packages/table-devtools/src/styles/use-styles.ts, packages/table-devtools/tests/FeaturesPanel.test.tsx, .changeset/lean-trees-shake.md
The panel uses the size catalog and estimator to show core, feature, row-model, and built-in function sizes. It reports custom functions and shared-code-aware totals; tests check the rendered size labels.

Merge Risk: 🔵 Low · up to 37b58

The change is mergeable with a minor cleanup follow-up: failed bundle-size generation can leave small files in the system temporary directory. No material table behavior or size-reporting failure was established.

212-398: 📐 Maintainability & Code Quality | 🔵 Trivial | 💤 Low value

Remove the temp directory in a finally block.

Line 212 creates tempDir. Line 398 deletes it only on the success path. If build, measureDeclarations, or brotliOf throws, the script exits and leaves table-bundle-sizes-* directories in the OS temp folder. The leftover directories are small, but each failed run adds one. Wrap the declaration-measurement phase in try { ... } finally { await rm(tempDir, { recursive: true, force: true }) }.
