Per @Snaevar's [[https://en.wikipedia.org/wiki/Wikipedia:Village_pump_(technical)/Archive_177#Wikitable_header_centering:_desktop_vs_mobile|suggestion]], I'm reporting the following bug:
> Wikitables set with a global alignment in style will show headers centralised on desktop and according to that global alignment on mobile.

**Steps to Reproduce: **
Set //style=text-align:right// (or //left//) at the wikitable declaration line. Check whether headers are right (or left) aligned on both desktop and mobile modes.
**Actual Results:**
Headers show centralised on desktop, and aligned right (or left) on mobile.
**Expected Results:**
Being used to editing WP in desktop mode, I expect headers to be centralised on mobile mode as well (unless specifically told otherwise (but I could also get used to the reverse convention: global style applies to all, including headers, which are easy to recentralise with a row style, if need be).
