@djinnome ipydatagrid is compatible with JupyterLab 3. Please follow the instructions in https://github.com/bloomberg/ipydatagrid#installation as well.

@djinnome Apologies - the instructions published initially were outdated. pip install ipydatagrid should be enough when using JupyterLab 3. It is important to note we only support JupyterLab3 for now!
