Okay, your example of using bulletted items was very helpful.  But here is
another case.

I want to write a letter, and I want to put an address in the top right
corner.  Now the way I was thinking of doing this was to use a table to
push it over (This way I can have one cell in the left with my address,
and a cell in the right for the receipient's address).  But the amt. I
want to push it over depends on how wide the address I'm sending to is.

Thanks for any help.
