Your use of the word "table" is throwing me a bit. The raw power pivot table obviously came from somewhere... (sql, csv, power query, sharepoint list, whatever you did there). So you could probably just use that? I suppose the calculated columns might be an issue. But it's not like there is a way to "export a powerpivot table to sharepoint" so I'm not totally getting your question.
The workbook itself can be hosted on sharepoint, of course. Even there though, the only excel services would display is data from actual excel worksheets (say, pivot tables you built from your powerpivot model).
Maybe rephrase your question?
