Add Text in New Column with Rowspan on Invoice

[Starlight Design]

Hello. I have searched the forum for working with columns, but haven't found exactly what I'm looking for. I need to add extra text on the invoice.

 

1. on the right of the invoice number, in the same font

2. on the right of the invoice date/due date, taking up those 2 rows, in a much larger font

 

I have attached an image of what I'm trying to accomplish. I don't see any documentation on the $pdf->Cell stuff but I can tell it creates a complete row, and I need to get in there and rearrange things a bit.

 

Here is why I'm trying to do. The blue line is just to show how things are aligned. Thank you for any tips.

ok I did find some documentation on the cell function, but am still not sure exactly what to use and how I'd get the BIG TEXT to take up both rows, as shown.
