I’ve got simple and basic dynamic row height resizing working for a DataTable. My code resizes the row heights based on the content. You can’t size each row individually, but you can resize all rows for the maximum size you need.
The example is based on the Gallery example: bokeh/examples/app/export_csv at branch-3.0 · bokeh/bokeh · GitHub
My code is here: CodeExamples/tablerowheight at master · MikeWoodward/CodeExamples · GitHub
