Before	After

Prerequisites

• Browser: Chrome 120+ (tested), Firefox 122+, Edge 120+
• Tampermonkey: v4.20+ (required)
• Verified on: Windows 11
• Perplexity.ai UI changes frequently. If the script stops working after a site update, see Troubleshooting and open an issue with details.
• Violentmonkey and Greasemonkey have not been tested. They may work, but they are not officially supported by my testing at this time.

Installation

Option A: Installer (auto updates)

1. Install the loader script:
   https://github.com/IanWardell/TamperMonkey-Perplexity-Full-Width-Tables/raw/refs/heads/main/TamperMonkey-Installer-Perplexity-Full-Width.user.js
2. Open any Perplexity.ai page. The loader fetches and runs the latest main script automatically.
3. Optional: In the Tampermonkey menu, click "Reload Perplexity Full Width (fetch latest)" to force a refresh.

Option B: Direct install (fixed version)

1. Install the main script:
   https://github.com/IanWardell/TamperMonkey-Perplexity-Full-Width-Tables/raw/refs/heads/main/perplexity-full-width.user.js
2. Direct installs do not auto update. Reinstall to get new versions later.

Verify

• Open a Perplexity.ai answer that renders tables.
• Open the DevTools Console and confirm you see log lines prefixed with [PerplexityWide].
• Resize the window. Tables should fill the available width and scroll horizontally when needed.

Configuration and debug

• The main script has a DEBUG toggle near the top: const DEBUG = true;.
• With DEBUG enabled, the console shows detailed messages with the [PerplexityWide] prefix.
• To temporarily disable the script, toggle it off in the Tampermonkey dashboard without uninstalling.

Permissions

• Installer script:
  • Uses GM_xmlhttpRequest to fetch the latest code from GitHub.
  • Requires @connect for raw.githubusercontent.com, githubusercontent.com, and github.com to allow fetching updates from GitHub.
• Main script:
  • Uses @grant none.
  • Does not make network requests or collect data.

Troubleshooting

Most breakages occur when Perplexity updates class names. Always check the "Scope and selectors used" section first.

• Force reload the page with cache bypass:
  • Windows: Ctrl+Shift+R
  • macOS: Cmd+Shift+R
• Make sure the script is enabled in Tampermonkey and runs on *://*.perplexity.ai/*.
• If elements still do not stretch:
  • In the Console, confirm [PerplexityWide] logs appear.
  • Paste the following in the Console to check whether the targeted selectors exist:
    document.querySelectorAll('div.group.relative, div.group.relative.flex, .min-w-full, .min-w-0, .gap-sm.grid > .min-w-0, .line-clamp-1').length
  • If the count is 0 or unexpectedly small, Perplexity may have changed CSS classes.
• When reporting an issue, include:
  • Example URL, steps to reproduce, browser version, Tampermonkey version
  • Console output with DEBUG enabled
  • A screenshot of the relevant DOM structure if possible

Scope and selectors used

The script currently adjusts width and overflow on:

• div.group.relative
• div.group.relative.flex
• .min-w-full
• .min-w-0
• .gap-sm.grid > .min-w-0
• .line-clamp-1

These class names are subject to change by Perplexity. Breakage is most likely when the service renames or restructures its grid wrappers or table containers.

Versioning

• Semantic Versioning:
  • MAJOR for breaking changes in behavior or configuration
  • MINOR for new features and selector expansions
  • PATCH for fixes and non-breaking tweaks
• Installer users get new versions automatically.
• Direct install users must reinstall to pick up updates.

Uninstall or disable

• Tampermonkey Dashboard > locate the script > either:
  • Toggle the switch to disable
  • Click the trash icon to remove

Security and privacy

• The main script does not send network requests and does not log or transmit user data.
• The installer only fetches the code from this GitHub repository.

Contributing and issues

• Open issues with:
  • URL and steps to reproduce
  • Browser version and Tampermonkey version
  • Console output with DEBUG enabled
  • Screenshot or snippet of the changed DOM if known
• Pull requests should:
  • Keep the logging prefix consistent: [PerplexityWide]
  • Avoid adding dependencies
  • Include a brief note in the changelog
