The 'Plan summary table format' function within a Report Theme allows you to configure how the Plan Summary tables come out at the top of the review and recommendation sections in your reports.
The default option is 'Dynamic'. When this is selected, Plan Summary tables with seven or less fields will be rendered horizontally.
However, those with eight or more will be automatically rendered vertically.
If you'd prefer the Plan Summary tables to always be rendered horizontally, irrespective of the number of fields included, select 'Fixed horizontal'. However, please beware that tables with lots of fields can soon look very busy and text can leach over multiple lines when rendered horizontally.
