AdvancedReport::getDuplicatedBlankingFields
Get a list of columns that should have subsequent duplicated entries 'blanked' out
This is used in cases where there is a table of data that might have 3 different values in the left column, and for each of those 3 values, many entries in the right column. What will happen (if the array here returns 'LeftColFieldName') is that any immediately following column that has the same value as current is blanked out.
