Tabulator.info cellClick & Processwire API

[kater]

I'm using Tabulator (5.3 http://tabulator.info/docs/5.3/data) with current PW.

Maybe someone knows a smarter/faster way to change PW field values of a page via single click (not opening the edit dialog for the specific page) and can point me there?

Now (very slow):
(Backend) tabulator cellClick:function() calls js function and mutates cell value (symbol) for instant feedback.
Js function calls php function which API edits PW page.
Rebuild Page/Tabulators based on edited field value.

Thanks!
