Cross tabulations are statistical reports where you de-normalize your data and show results grouped by one field, having one column for each distinct value of a second field.
Basic problem definition. Starting from a list of values, we want to group them by field A and create a column for each distinct value of field B.
The desired result is a table with one column for field A, several columns for each value of field B, and a total column.
