Number of crosstab columns generated per "block"

[rlfisherpbtgroup.com]

When a crosstab has many columns, and the page width is narrow, the crosstab is naturally folded into multiple blocks (when we are exporting, for example, to Excel we ignore the width and get one very wide report).

We have noticed that, for an example report... there are 36 columns.  7 columns fit the page width.  The blocks contain 7-7-7-7-4-4 columns, instead of the 7-7-7-7-7-1 we expected.

Is there a crosstab algorithm that tries to avoid orphan columns?  Can it be overridden?

thank you
