Records summed up by the fields people choose: rows grouped by one or more fields that fold open level by level, columns split by another, one or more measures (sum, count, average, min, max) in every cell, subtotals on every group and totals at the end; fields move between Rows, Columns and Values from a menu on each chip, the table rearranges with rows sliding to their new places, cells can be shaded by their size, and a cell with no records stays blank while one whose values were never measured is hatched. (Beamline complete system)
