Hi Q,
Currently, we only support two format types with copying and pasting multiple cells. One is Text and the other is our internal style format. If you want to support an additional format(CellValue instead of Formatted text), you would have to implement it yourself. You would catch the ClipboardCopy event, and do your work there. Here is a forum thread discuss with the simillar issue.
