Is it possible to append options dynamically to a dash datatable dropdown like a regular dash component dropdown as described in [this](https://github.com/plotly/dash-recipes/blob/master/dash-append-element-dropdown-options.py) example?

The use case is this:  
When I append new rows to a datatable, it want to be able to select all the id’s of the rows in a dropdown in another column.

Hope it make sense.
