Does anybody know how to put an external file (like www.externalfile.com) into a table which is on asp-page?

Which kind of file you want to include?
Your example www.externalfile.com is quite confusing as it looks more as a web address.
If you are talking about images you can simply put the link to it like www.someweb.com/image.jpg.

I ment something like: www.example.com/thispage.htm

One way is of course just inserting HTML code in your table like this:

..bla..bla..<a href="yourpage.asp">Yourlinkname</a>..bla..bla..

If it's an internal file the use the correct relative or absolute path, if external use the full URL.
Good luck,
