I see a note that longtables are possible. I have a book that needs longtables and sideways table facility like in LaTeX. If it is possible could someone please point me in the correct direction?

You can rotate tables with the float mechanism:

\placetable
  [90,more settings]
  {<Caption>}
  {<Table>}
