Pre-built Data Table Component (Website)

Design Handsontable
Handsontable provides a production-ready, Excel-like data grid component built to solve complex UI performance and accessibility challenges at scale.
What: Handsontable offers a data table component featuring virtualized scrolling for large datasets, Excel-style keyboard shortcuts, and custom cell renderers designed for enterprise B2B applications.
Why it matters: Building high-performance data grids in-house is notoriously difficult due to layout thrashing and DOM complexity, making pre-built, battle-tested components a common choice for SaaS teams.
Deep dive
  • Virtualization: Renders only the visible portion of the table, keeping the DOM size small.
  • Layout Thrashing: Occurs when code repeatedly reads and writes to the DOM, forcing constant browser recalculations.
  • Excel Formula Parser: Includes a custom engine to calculate formulas directly within the browser.
  • Accessibility: Implements WCAG 2.1 AA standards including ARIA attributes and keyboard navigation.
Decoder
  • Layout Thrashing: A performance issue where rapid read/write sequences to the DOM cause the browser to perform unnecessary recalculations of page layout.
  • Virtualization: A technique where only the elements currently visible on the screen are rendered in the DOM, allowing grids with thousands of rows to remain performant.
  • DOM (Document Object Model): The tree-like structure of HTML elements that a browser uses to render a webpage.

What our customers say

See why companies large and small love using Handsontable in their business apps.

„It only took us a few hours to integrate Handsontable compared to doing it ourselves and putting in weeks of effort to create a table input area.” — Berry van Elk, Founder/CEO at Maglr
„We have the table in the middle, and we've built our product around it. Handsontable is easy to implement, well documented, really customizable, and just good for our purpose.” — Ben Hartig, Co-founder/CTO at nuvo
„With Handsontable's help, we had our app set up in a matter of a week or two. It was easy to integrate with our software, it has comprehensive documentation, and it supports a lot of use cases that we need.” — Diego Oliveira Sanchez, Co-founder at Magosoft

Building a data table UI starts easy... but quickly turns complex.

  • Performance Engineers struggle to keep the UI responsive when rendering grids with thousands of rows and hundreds of columns.
  • DOM Size A large DOM tree leads to slow style recalculation and a high memory footprint, degrading overall application performance.
  • Virtual Scrolling With virtualization, it’s challenging to prevent state loss on re-render and keep the scrollbar position accurate - especially when dealing with dynamic item sizes or drag-and-drop.
  • Browser Support Ensuring a consistent UX and visual fidelity across the latest stable and beta versions of Chrome, Firefox, Safari, and Edge requires constant testing and mitigation.
  • Accessibility WCAG 2.1 AA compliance is a challenge that involves the correct use of ARIA attributes, a proper color contrast, and a sufficiently large hit area for interactive elements.
  • Security Audit Passing a rigorous security audit, including static and dynamic analysis against standards like the OWASP Top 10 and OWASP ASVS, is essential for enterprise adoption.
  • RTL Properly supporting right-to-left languages requires a significant, non-trivial effort to mirror the entire UI layout and interactions
  • Internationalization Supporting a global audience means handling not only translations but also complex date and number formatting across different locales.
  • Unicode Input (IME) Ensuring the component correctly handles characters and composition events from a Unicode input (IME) is a common internationalization challenge.
  • Layout Thrashing Repeatedly reading layout properties and then writing to the DOM in a loop causes - a performance bottleneck.
  • Costly Re-renders A key optimization challenge is to implement DOM subtree reuse to prevent costly re-renders of components that haven't changed.
  • Excel Formula Support Implementing robust Excel formula support requires a sophisticated parser that understands the correct syntax and ideally adheres to a standard.
  • Content Layout Shift Dynamically rendered content can cause an unexpected CLS, disrupting the user's reading flow and interaction.

Handsontable gives you the battle-tested data table you’ve been waiting for.

Whether you're building B2B SaaS products or internal tools for a Fortune 500, create the exact UI you need — without the heavy lift.

A data table experience that feels like Excel

From keyboard shortcuts to custom functions, Handsontable delivers the table experience users expect without sacrificing app reliability. You get full control. They get the familiarity they need.

  • Excel experience + over 400 formulas Familiar keyboard shortcuts plus autofill.
  • Quick editing Inline editing, copy and paste, undo/redo.
  • Row and column operations Sorting, filtering, grouping, freezing, moving, hiding, and more.
  • Custom cells Ability to implement any renderer, editor, conditional formatting or validation rules.

Fits right into your design system

Handsontable is built for full customization, using design-tokens to connect design and code. Make it look like your product — not ours.

Unmatched virtualization performance

We’re the only data table with virtualization for scrolling on both axes, plus support for dynamic row heights, any DOM container, or main window scrollbar.

We tackle maintenance for you

Our expert team handled 1000+ tickets last year with speed and precision. We use a dedicated multi-device lab, QA, and regression testing to ensure your table never breaks.

Accessibility that stays ahead of the curve

We continuously align Handsontable with global accessibility standards and test across browsers, assistive technologies, and environments. From keyboard navigation and semantic markup to screen reader support, your data grids are built to be inclusive and remain that way as standards evolve.
