SQL Kernel and Pandas table widgets do not display when re-opening a JupyterLab window

If you navigate back to a still-running notebook with output in the table widget in Jupyter Lab, different error messages display, depending on Jupyter version. In 0.33, it looks like this:
`No (safe) renderer could be found for output. It has the following MIME types: application/vnd.jupyter.widget-view+json, method`

Is there a way to make this load the widget correctly, or to fall back to a static (non-widget) display when re-loading a page you've previously visited?

The static fall-back would be extra neat because it might allow results to be viewable in a console window too, and not just in the notebook.
