Occasionally I have the need to enter longer than usual text segments into my
spreadsheets that include tables and text formatting that is available only
in rich text formats.

1) Is there any way to add this functionallity to excel via plugin or other

2) Is this feature available on any version of excel?  I am using excel 2003.
