I guess it depends on how much you need to do to the data.  Platypus is
really good at managing documents that consist of a series of
"flowables".  If your data can be arranged in a series of things of
variable height that are page-wide, then what you ask is pretty easy. 
You can just derive your own class from Paragraph and lay things out
yourself.

If you need spreadsheet-like functionality, where things need to break
within cells and cells can be arbitrarily large, that's where things get
really tricky.
