embedding iframe html into a post?

I'm trying to create a thread in tech-talk which would reference data stored in a public google-doc. Google creates iframe html code to embed a doc into a web page. There is too much data to create a table in the post itself or else I would be doing that. My only idea at the moment is to take a screen-shot and upload the image. Is there a better way?

here is a link to the data:
https://docs.google.com/spreadsheet/...25&output=html

and here is the iframe code:
<iframe width='500' height='300' frameborder='0' src='https://docs.google.com/spreadsheet/pub?hl=en_US&hl=en_US&key=0AtJMZwK3kkVkdGZnN0x4OGZ DaFkwdGZXSWVyVWVROGc&single=true&gid=0&range=a1%3A y25&output=html&widget=true'></iframe>
