CHAPTER 17. TABLE FORMATTING


17.3.2 Row and Column Formatting Protocol

Any output record class that implements the following generic functions is said to support the
row (or column) formatting protocol.

=> row-output-record [Protocol Class]
The protocol class that represents one row in a table; a subclass of output-record. If you
want to create a new class that behaves like a row output record, it should be a subclass
of row-output-record. Subclasses of row-output-record must obey the row output record
protocol.

=> row-output-record-p object [Function]
Returns true if object is a row output record, otherwise returns false.

=> standard-row-output-record [Class]
The instantiable class of output record that represents a row of output within a table. Its
children will be a sequence of cells, and its parent (skipping intervening non-tabular records such
as presentations) will be a table output record. This is a subclass of row-output-record.

=> map-over-row-cells function row-record [Generic Function]
Applies function to all the cells in the row row-record, skipping intervening non-table output
record structure. function is a function of one argument, an output record corresponding to a
table cell within the row; it has dynamic extent.

=> column-output-record [Protocol Class]
The protocol class that represents one column in a table; a subclass of output-record. If you
want to create a new class that behaves like a column output record, it should be a subclass of
column-output-record. Subclasses of column-output-record must obey the column output
record protocol.

=> column-output-record-p object [Function]
Returns true if object is a column output record, otherwise returns false.

=> standard-column-output-record [Class]
The instantiable class of output record that represent a column of output within a table. Its
children will be a sequence of cells, and its parent (skipping intervening non-tabular records such
as presentations) will be a table output record; presentation output records may intervene. This
is a subclass of column-output-record.

=> map-over-row-cells function column-record [Generic Function]
Applies function to all the cells in the column column-record, skipping intervening non-table
output record structure. function is a function of one argument, an output record corresponding
to a table cell within the column; it has dynamic extent.
