I don't understand why you are use two methods for sorting columns (qsort, and query with ORDER BY) 2. Data column are not well aligned - numbers are aligned as text 3. When data are multiattribute - then merging together with space separator is not practical * important information is lost * same transformation can be done as expression, so this feature is useless Is possible to use one cell per attribute (don't do merge)? DATA QUERY: SELECT dim1, dim2, sum(x), avg(x) FROM .. GROUP BY dim1, dim2 and result header of rotate can be DIM1 | dim2_val1/sum | dim2_val1/avg | dim2_val2/sum | dim2_val2/avg | ...
