I have multiple tables in a word template and need to change each of it in an other way. Also it is possible that one or the other will be deleted or inserted so I can't say I take the 5th and that's always the same one.  

The identification has to be saved so I can't use the .ID value. 

What way is there to identify a specific table with VSTO? Preferable one which can also be set in the document without VSTO.
