CellEncoder

Encodes values of type A into CSV cells.

CellEncoder instances aren't meant to be used directly, but rather provide the backbone of the RowEncoder mechanism.

If you're working with data that contains dates and need to serialise these to valid ISO 8601 strings, for example, you'll need to create a custom CellEncoder[Date]:

implicit val dateEncoder = CellEncoder((d: Date) => new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ").format(d))

Once this is done, tabulate will be capable of serialising date fields without any further work. The following, for example, will create a RowEncoder for triples of type (Int, String, Date):

RowEncoder[(Int, String, Date)]
