Inserting table on a footer

How to do the following:

·         Insert table in the footer on the project you are working on then type your revision text , e.g. prep by, reviewed by & Approved by etc. on the table into the various columns.

·         When you switch to another project,  the inserted table becomes your default. So you are required to  edit the columns e.g.  the person who approves project A will be different from the one that approves project B. So we are required to just edit that column. But this not the case.
