You can use the fact that the notebook can display html for objects, and data urls, to make the content of a csv downloadable:

import urllib

class CSV(object):
    def _repr_html_(self):
        html = []

        html.append("{},{},{}".format(
                "user",
                "age",
                "city"
            )
        )

        html.append("{},{},{}".format(
                "Alice",
                "39",
                "New York"
            )
        )

        html.append("{},{},{}".format(
                "Bob",
                "30",
                "Denver"
            )
        )

        html.append("{},{},{}".format(
                "Carol",
                "27",
                "Tulsa"
            )
        )


        export = '\n'.join(html)
        export = urllib.quote(export.encode("utf-8"))
        csvData = 'data:application/csv;charset=utf-8,' + export
        return "csv file".format(csvData)

CSV()
