How do I add a table to an RFP?

You can add a table you've created from your library and drop it into any desired section while creating an RFP.
 

From the RFP outline click the question that you'd like to add a table response type.

 

On the right-hand side, choose the Response Type Complete a Table from the Action Menu dropdown. Select the appropriate table and then click Update Question to save changes. 
 

Once you have added the table, you are able to modify it by adding or deleting rows and columns.
