    Answer ✓

    You have serverSide enabled, so all sorting, fitlering and paging need to be done by the server.

    If you have less than 10k rows, then just remove the serverSide option. If you have more than that, then have a look at this blog post which shows how you can use our Editor libraries to do server-side processing. Or your can implement it yourself using the manual page I linked to above.
