Thanks! Do you see an error in the JavaScript console?

using a fresh env

mamba create -n dg-jlab4 jupyterlab>=4 ipydatagrid pandas

[martinRenou]

So it looks like ipydatagrid uses this createCellConfigObject function that is private API from Lumino, this function may have been renamed or removed in Lumino 2, resulting in it not working for JupyterLab 4.

It looks like this function stopped being exported in jupyterlab/lumino@f4feada

A bit of a shame that it was introduced in the first place as a private function . . .

Agreed, thanks a lot for pushing PRs for this!
