embed numbers spreadsheet into a webpage

Hi all,

I would like to know if it is possible to embed online numbers spreadsheet into webpages as google docs do.

I tried to use <iframe> tag into html webpage and pasted inside the shared iCloud link but an error occurred:

iWork Editor encountered an error and is no longer usable.

Error: Error: TypeError: undefined is not an object (evaluating 'e.documentElement')

JavaScript console contains more details.

Can someone help me?

Thanks in advance

F.
