Table Component sits at the heart of data display in design systems. This guide walks through the concept step by step, with examples, a cheatsheet, and common mistakes to avoid.
Table Component Overview
Table Component lets you structure design systems work so it stays readable, testable, and easy to scale. Instead of ad-hoc code, you follow a clear pattern that other developers can recognise immediately.
The key is to keep table component focused and predictable. Start from the minimal example here, then layer in only the complexity your feature actually needs.
<ds-card>
<h3 slot="title">Plan</h3>
<p slot="body">Everything your team needs.</p>
<ds-button slot="actions" variant="primary">Choose</ds-button>
</ds-card>
Slot-based composition lets consumers place content while the component controls structure and style.
Table Component Example
/* Tokens flow into components, which flow into products */
:root { --color-brand-500: #2563eb; }
.button { background: var(--color-brand-500); }
Start from a minimal Table Component example and grow it only as needed.
Keep configuration explicit so Table Component behaves the same in every environment.
Name things clearly so teammates understand your Table Component at a glance.
Add tests around Table Component early to lock in expected behaviour.

How Table Component Fits into a Design System
Table Component connects the design decisions in your system to the code teams actually ship. When it is defined once and reused, products stay consistent and updates roll out everywhere.
Slot-based composition lets consumers place content while the component controls structure and style.
Define it once as a token or shared component.
Document intended usage with clear examples.
Make it themeable and accessible by default.
Version and release changes so consumers can upgrade safely.
Getting Teams to Adopt Table Component
Adoption is where design systems succeed or stall. Make table component the easiest option: great docs, sensible defaults, and clear migration paths beat mandates every time.
Lever
Why it drives adoption
Documentation
Teams use what they can understand quickly
Defaults
Accessible, on-brand results with zero config
Tooling
Linting and codemods reduce migration cost
Support
A responsive team builds trust
Common Mistakes
Skipping error handling and edge cases when wiring up table component.
Leaving table component untested, so regressions slip into production.
Over-engineering table component before you actually need the extra flexibility.
Ignoring documentation, which makes table component hard for the next developer to change.
Key Takeaways
Table Component is a core part of working effectively with design systems.
Start small and keep table component focused on a single responsibility.
Apply consistent patterns so table component scales across your project.
Test and document table component to keep it maintainable over time.
Pro Tip
When you get stuck on table component, reduce it to the smallest reproducible example first — most design systems issues become obvious once the noise is gone.
You now understand table component in design systems and how to apply it in real projects. Next, continue with Data Grid to keep building your skills.
