Yes it's theoretically possible. I created an example of linking a table to a scatter plot brush selection. That said, I have never been able to get altair/vega-lite to generate a nicely formatted table to my satisfaction. I mostly end up connecting a simpler altair chart without interactions to a dataframe and hook them together using something like ipywidgets, Panel, or streamlit. It would be really nice though to be able to get the table linked to native altair interactions like selection and brushing.
