How do you auto adjust columns in a crosstab

[Gemma3004]

I have set up a crosstab.  The row is a 'Question' and the column is a 'Person', the measure is the 'Answer' to the question.

There could be upto a max of 4 columns becuase there could be 4 persons providing their own answer to the question.

How do I set up the crosstab so that depending on the columns/Persons, the columns resize equally to the width of the page?  So if there are only 2 columns/persons, then they should be equally spaced across the page and if the are 4 columns/persons, then again all columns should be equally spaced across the page.
