Can you pass a DataTable through a callback?

Dash Python

I want to be able to create a DataTable and pass it, so I can continuously create a DataTable that has a dynamic set of columns.

If I select 3 column names in a multi-dropdown, for example, I’d like to create a DataTable with just those 3 columns.

@app.callback(
    [Output('count_table', 'children')]
    [Input("slider", "value"), Input("statuses", "value")]
)
def update_table(slider, statuses):
    df = filter_dataframe(data, slider, statuses)
    return dash_table.DataTable(
        columns=[{"name": i, "id": i} for i in df.columns],
        data=df.to_dict('records'),
    )

Is this possible to do? Is there another way I can do this other than passing a DataTable through a callback?

Yes that should be possible. Another way would be to update the columns and data attributes (of a pre-defined data table) in a callback.
