react-doctor/prefer-tabular-numeric-data

Changing table numbers use proportional figures

  • Category: Maintainability
  • Severity: warn
  • Source: oxlint-plugin-react-doctor
  • Framework: global
  • Enabled when: always
  • Tags: design, test-noise
  • Default: Disabled until configured

Validate the diagnostic

Confirm the reported code matches this rule before you edit it.

Confirm the reported code matches react-doctor/prefer-tabular-numeric-data. Compare it with the Before example and verify the same API, framework, and execution context. Treat it as a false positive only when one of those conditions differs.

Compare the code

The corrected pattern shows a focused way to address the diagnostic.

Reported pattern

<td>{latency.toFixed(2)} ms</td>

Corrected pattern

<td className="tabular-nums">{latency.toFixed(2)} ms</td>

How to fix

Use the corrected pattern as a reference. Preserve behavior that the rule does not require you to change.

Copyable fix prompt

Copy this self-contained prompt into your coding agent after you confirm the diagnostic.

Fix every confirmed react-doctor/prefer-tabular-numeric-data diagnostic in the current repository. Required change: - Apply tabular-nums to dynamic numeric columns so digits keep a stable width and align while values change.
Reference transformation:Before:
<td>{latency.toFixed(2)} ms</td>
After:
<td className="tabular-nums">{latency.toFixed(2)} ms</td>
Constraints: - Confirm the reported code matches the Before pattern. - Make the smallest change that fixes the root cause. - Preserve behavior and interfaces unrelated to this diagnostic. - Reuse existing project components, utilities, and conventions. - Do not introduce render-phase side effects, render-phase state updates, or Hooks rule violations. - Use existing brand assets, product facts, content, and design tokens. - Do not invent claims, customer data, typefaces, or artwork. - Adapt identifiers and framework details instead of copying blindly. - Do not disable the rule or suppress matching code. Verification: - Run focused tests for the changed behavior. - Run React Doctor and confirm this diagnostic no longer appears. - Report the files changed and any checks you could not run.
