How do I use a TextInput from the user to download in a CSV file the top N rows sorted as per the users sort from a Bokeh DataTable?

@Bryan From what I understand, this is me sorting the CDS as I would like. But what I would really like is for the CDS to be sorted according to the sort (order) of the DataTable. So for example, if I sorted the DataTable by the column ‘a’ by clicking on the column name (header) in the DataTable and then clicked download I would want that order to be retained in the CSV file. I think what I want is similar to this: Attribute that captures the ordering of the data in a bokeh DataTable

Once I understand that we are on the same page, if you still think it is reasonable to open an issue, I would be more than happy to do that.

Thanks for being so responsive!
