Communities header columns are links but do nothing
The header columns (Name, Subscribers, Users/month, Post, Comments' on the 'Communities' page appear to be hyperlinks (Firefox 114.0.1) but do nothing.
Normally, you'd expect the table to be sorted on the field.
You're thinking of DataTables. The lemmy-ui source code shows the css class as
table. It looks to me like the basic bootstrap table.Correct. This is part of the Lemmy Web-UI and not something that SDF can address unless they fork the project. The page will likely be improved with time, as is usually the case with open-source projects.
For now, you can sort communities by their statistics using the browser at: https://lemmyverse.net/communities
