Converting logical column numbers to physical row and column
numbers is straightforward: the physical row number is
the logical column number divided by
MAX_PHYS_COLS, and the physical column number is
Here, we distribute the suffix cells over the physical rows,
but starting at a logical column number (
logBase) such that the last suffix cell lands in the last cell of
the last physical row. We use the virtual
.suffixes() method from the concrete instance to
retrieve the material that will appear in those positions; see
Section 29, “
class Row: Abstract class for logical
rows” for the interface definition.
