Chapills,
You've got two really viable options. First, with your document loaded up in Word, go to your File menu, select "Save As" and save the file as Rich Text Format (.rtf). It will save 90% of your formatting, including tables.
The second option is to have your friend go to the Microsoft website and download the Word 97-2000 Viewer (If that link doesn't work, go to downloads and search on viewers for Word.)
A third option is to go to this site and download their free PDF converter and "print" the file in PDF format. They'll need to have Acrobat Reader to read it, but it completely preserves all your formatting. They won't be able to edit the document, tho, just read it.
So ... it depends on what they want/need the file for.
Good luck!
