>Where would you have the extra width of the word go? - As far as I know, there is no such option; you just have to make the font sufficiently small, or the column sufficiently wide, or use hyphens. However, it seems that Excel has no "soft hyphen" feature, at least, not within cells. I am referring to the hyphens that only become visible if they happen to get to the end of the line.

Yes, but this is all generic. Users define the report on the Web site from the framework and that goes up to Excel. It is a matter of avoiding a single word to be broken, thus avoiding orphan, kind of.
