Linking one table to another table within a word document

Hi, I'm trying to link two tables together within a Word document. The only way that I was successful in doing this, was by linking it to an Excel workbook and using a new worksheet for each table. Unfortunately, I cannot use this method because of it's intended purpose. It became too confusing dealing with two documents rather than one. I either need to link the tables using embedded Excel worksheets or Word tables. It involves different formulas etc. Is there any way to do this? Thanks.
