@tanstack/table-core

About

Headless UI for building powerful tables & datagrids for TS/JS.

What detecting @tanstack/table-core tells you about a site

Table-core is the headless engine for TanStack Table, and its presence reveals an app with serious tabular data: think dashboards, admin consoles, analytics tools and data-grid-heavy SaaS. Headless means it ships logic for sorting, filtering, pagination, grouping and column resizing but renders nothing itself, so finding it tells you the team wanted full control over markup and styling rather than an opinionated grid widget. It is a signal of a product where displaying and manipulating rows of data is a core feature, and of engineers who preferred composing behaviour over fighting a pre-styled component.

Why the exact @tanstack/table-core version matters

TanStack Table's version 8 was a ground-up rewrite from the older react-table v7, moving fully headless and framework-agnostic with a very different API. Seeing table-core at all means version 8 or later, but the precise version still matters for which features like row pinning, faceted filtering or column sizing modes are available and how the state model is shaped.

@tanstack/table-core in a real-world stack

When you find @tanstack/table-core in a bundle, it rarely travels alone. A framework adapter such as @tanstack/react-table, and frequently @tanstack/virtual for windowing large row counts.

Quick facts

What @tanstack/table-core pulls in

@tanstack/table-core declares 1 direct dependency — each one also rides into any bundle that ships @tanstack/table-core, so they are detection targets too. Reading them is a quick way to understand the package's real footprint .

How Sourcemap Explorer detects @tanstack/table-core

@tanstack/table-core ships as v9.3.1, published 2026-10-12 and carries 1 direct dependency, 298 versions on the registry. Those exact numbers are the footprint Sourcemap Explorer matches when @tanstack/table-core rides inside a deployed bundle — here is how the detection works.

We catch @tanstack/table-core from two complementary signals: bundled source paths and the embedded package.json. Modern bundlers (webpack, Vite, esbuild, Rollup, Turbopack) preserve the original node_modules/@tanstack/table-core/ paths inside the JavaScript sourcemap's sources[] array — that's the canonical signal. When the matching package.json is also captured in sourcesContent[], we read the exact version field — patch number included. No regex guessing, no version inference.

1. 1

   Confirm the site exposes sourcemaps

   In DevTools Network, check the response headers of any application script for `SourceMap` or `X-SourceMap`. Failing that, fetch the script's last 4 KB and look for a `//# sourceMappingURL=` comment — that map is where the `@tanstack/table-core` paths live.

2. 2

   Find the package in the bundle

   Open DevTools → Network → reload. Click any application script and look at its sourcemap. Inside, search `sources[]` for entries matching `node_modules/@tanstack/table-core/` — every match confirms the package is bundled. The matching `sourcesContent[i]` for `node_modules/@tanstack/table-core/package.json` gives you the exact installed version.

3. 3

   Read the version directly from package.json

   Run `jq -r '. as $m | $m.sources | to_entries[] | select(.value | endswith("node_modules/@tanstack/table-core/package.json")) | $m.sourcesContent[.key] | fromjson | .version' bundle.js.map`. Sourcemap Explorer automates the same query in the popup.

Major releases of @tanstack/table-core

When each major version first landed. Major bumps are where breaking changes live, so this timeline is the fastest way to date the @tanstack/table-core version a site actually ships against the ecosystem.

Using an AI Coding Agent?

TanStack Table ships TanStack Intent skills inside each adapter package. After installing the library, run:

npx @tanstack/intent@latest install

to add skill-loading guidance for your agent (Claude Code, Cursor, Copilot, etc.). The same CLI also exposes intent list to browse available skills and intent load <skill> to print one for inspection. Skills are versioned with the library — your agent gets guidance that matches the version of @tanstack/<framework>-table you installed. Only available for v9 and above.
