There'shttps://www.drupal.org/project/tablefield, which allows setting up a field on content types (or on a block that could be placed using layout builder) that you can upload a CSV or enter data manually. With the data in a specific field, it should be relatively easy to add any of a bunch of different Javascript libraries -- it mentions “tablesorter” but that looks unmaintained. Here's a list of 19 different libraries, most of which should work:https://flatlogic.com/blog/top-19-remarkable-javascript-table-libraries-and-plugins/... I've used Vuetify datatables, but had to move away because they didn't get a version for Vue3, and Ag-Grid. 

We can create a “Single Directory Component” for this to use any of those libraries. There's a bunch of other features these can include, although tablefield itself doesn't have any provision for paging data, so probably not the way to go if you're dealing with more than a couple hundred rows.

Some of those Javascript table libraries can “decorate” existing HTML tables. So if these are small tables just copied and pasted into the wysiwyg, we could provide the necessary code to add a sorting function likehttps://github.hubspot.com/sortable/docs/welcome/. There are probably a couple other JS options that could also be used this way. This is the most finicky way to do it, and fairly easy for editors to accidentally break if they're not careful -- but on the other hand, tables can be easily interspersed this way inside a long article.

So it boils down to where the data is coming from, where they want to show it, how much data there is, and how they want to manage these tables!
