I did a huge deep dive on HTML/Javascript table libraries when I started working on Polar - which is a document management platform for PDF and cached HTML content (https://getpolarized.io/)
Right now we're using React-Table (https://react-table.js.org/)
I didn't actually see Tabulator when I did the full comparison and this seems to be right up there with Tabulator.
Table support is hugely important for us. We have to render the list of PDFs and documents you're managing, sort them, and also not necessarily have to render them all on the same page, so having pagination is insanely important.
There's a few things react-table doesn't do a very good job on including key bindings so I'm going to have to take a look at this library too.
