As told in detail there about something similar to your question Display specific sheet with edit mode in iframe
I would like to tell you that you can do this and even with live data too.
You just have to go to your sheet > File > Share > Publish to web > then embed code > copy code and paste to your site
Then add the below code to your code.
rangle=A1%3AB19
For selecting data of a specific range (A1 and B19 is a range, so change them accordingly, but don't change "%3A" in it, as it works as : this symbol here, if you use: it will show an error.
As you are new, so I will give you a sample.
