Saving only a portion of webpage into a file

hello,
im working on a web application that generates dynamic data. My question is: i want users to be able to save the generated data, but not the whole web page, just a table in the web page that holds this data. I searched and found out that showing a “save as” dialog box is possible with javascript, with a method like: [COLOR=Indigo] onclick=”javascript: document.execCommand(‘SaveAs’,’1′,null);[/COLOR]. However, i coulnd’t find out how to change the document object (or is it possible?) or a trick to print just the table of dynamic data. I tried to cover the table with <div id=”myData”></div> and use [COLOR=Indigo] onclick=”javascript: myData.execCommand(‘SaveAs’,’1′,null);[/COLOR] but as you might guess, it didn’t work and gave this error message: “object doent support this property or method”. Indeed i dont have any idea what div tag can and can’t do, so it was just a meaningless try.
Anyway, do you have any suggestions?

thanks in advance,
