Insert live spreadsheets in rich text fields

It would be great to incorporate prettier tables, but more importantly benefit from being able to perform sums on the go using a spreadsheet embedded in a rich text field.

Both office365 and google seem to allow this kind of functionality through the use of IFRAMEs:

With this, users could realise better financial analysis live within Aha! rather than repetitive copy and paste from Excel that quickly goes out of date.
