How to add a table in the Invoice template?

Hello,

We would need to add a table between the Date/TERMS/DUE DATE/INVOICE # table and the table that includes the Item/Description/Qty/Price/Discount/Amount table.

We need to add some text for one of our invoices and it does not fit in any of the templates.  I do have HTML function still with our account but cannot seem to add the table.  Do you have any suggestions on how I can do this?  I need to add it for 5 invoices that need to go out ASAP and this is a must that we have this available.  Any suggestions would be greatly appreciated.

Thank you. Jen
