Christmas Bird Count history report system

The maximum number of physical columns (excluding the column bearing the row labels) into which each logical row is folded when the detail table is rendered in Web form. A value of ten should be small enough to allow 8-digit numbers (see the Pine Prairie, LA count for numerous examples). Also, for counts that are run every year, the last digits of the year numbers will line up.

MAX_PHYS_COLS = 10

It is easy to request a report that has a large number of physical columns, but there comes a point when the ratio of detail rows to heading rows approaches unity. To discourage this, we put a hard limit on the number of logical rows.

COLUMN_COUNT_LIMIT = 200

Group the rows into groups of this number by thickening the borders around the group.

ROW_GROUPING = 4

Group the columns into groups of this number by thickening the borders around the group.

COL_GROUPING = 4
