Html.FormatterOutputs data in HTML form readable by many applications such as Gmail, Excel.
Datatype used is "text/html".
Note that when the clipboard content contains both "text/plain" and "text/html" datatypes, applications tend to prefer parsing "text/html".
val data_type : Datatype.tOutput returned by this formatter is of this datatype.
val create : ?border:bool -> unit -> Formatter.tCreate the formatter.
border adds 1x solid black border to the table. Default is false. Pasting content containing border to Excel preserves the border by default, because Excel uses "text/html" type. This can be circumvented by telling Excel to paste only values.
