I was struggling to get a Census table to fit my Booklet. Going Landscape A4 and editing the table still left a column off the page. I then realised that mimicking the Census form landscape table format was my problem, it would easily fit if I made it Portrait, there were fewer Individuals than Census questions.
So I created a second Table in the Text from Source Census Fact for the individual and then refreshed the book.
It was an easy fit.
In case it helps others with similar problems.
