Quickly change dates in a datatable

Is there a quicker way of changing a date in a ‘datetime’ column of a DataTable besides re-typing the entire YYYY-MM-DD? It would be nice if you could incorporate a single DatePicker in a dropdown function or even have arrows in the cell that you could use to increase/decrease the days of the date.

Has anyone tried this or something like it?

Any update on a a DatePicker dropdown that can be incorporated into a DataTable? Would be a really cool function if so.
