how can i make a static column/row in crosstab. For example below, can I have a fixed jan, feb, march, ... column instead of it generating dynamically? location jan feb mar apr may jun jul aug sep oct nov dec london 500 62 200 50 100 60 100 46 89 200 150 210 paris 50 26 20 500 50 70 40 200 70 40 250 50 I want the column (jan, feb, mar,apr,....) to always show up regardless of their measures zero or have values. Like they are fixed.
