Copy Rendered Table HTML To Clipboard, Not Text?

I have an issue where I am trying to allow the user to click on a table and automatically copy a table into the clipboard. I do this with text using IE:

function clickCopyText(fi) {
window.clipboardData.setData("Text",fi.innerText);
}

so to copy the table, I tried:

function clickCopyHTML(fi) {
window.clipboardData.setData("Text",fi.innerHTML);
}

The Trouble with Tables is the HTML itself gets copied as opposed to the rendered table. I am probably looking at some other way of getting the code to the clipboard, but I am stymied. I can do it with images, but not with rendered HTML.
