Does anyone know of something like this but with editable cells?

jqGrid, DataTables, ag-Grid, jQuerygrid, ... a lot. How many grid libraries do we need?

Tabulator, has most of the features of AG grid and is totally free http://tabulator.info/

Ag-grid

The best I’ve used so far. quite pricey, but worth it

Not pricey if you are ok with the open source MIT version.

Also their modular system is very easy to extend so you can always write your substitute adapters for their enterprise code without even forking it.
