User:PrimeHunter/Sticky headers.js

/* This script adds a link saying "Sticky headers" under "Tools".

The link reloads the current page with this gadget:

Make headers of tables display as long as the table is in view, i.e. "sticky"

(requires Chrome v91+, Firefox v59+, or Safari)

It displays incorrectly or poorly on some tables.

The gadget itself can be enabled permanently on the "Gadgets" tab at Special:Preferences.

This script should not be used if the gadget is enabled.

To remove the sticky headers again, navigate away in the browser,

e.g. with a back button or "Article" tab.

To use the script, add the following line to Special:MyPage/common.js:

importScript('User:PrimeHunter/Sticky_headers.js'); // Linkback: User:PrimeHunter/Sticky headers.js
