Hi Gregory,

In ref/Button, a 'roughly similar' example can be found:

Button["Delete Me", SelectionMove[ButtonNotebook[], All, ButtonCell];
 NotebookDelete[ButtonNotebook[]]]

So for example, I would have my button  programmatically find an 
appropriate location in a notebook to paste the table if one does not 
already exist. Otherwise, overwrite the cell with tag "RandomTable" 
using NotebookFind[] and NotebookWrite[].

I would also take a look at tutorial/ManipulatingNotebooksFromTheKernel 
which I found to be most useful for a project similar to yours.
