Quick Google search?
"To embed a spreadsheet or parts of a spreadsheet in a website or a blog, you'll need to publish it first. Here's how:
Open the Share menu in the upper-right corner of the page, and select Publish as a web page.
In the window that appears, select which parts of the spreadsheet you'd like to publish, and click the Publish now button. A unique URL is generated.
Use this URL to embed the spreadsheet on your website or blog."
I'm not sure that this will work. If not I hope someone who knows will help you!
