22 . A table is a rectangular grid of cells. Cells can be joined to form larger
23 cells. Rows and columns can be separated by rules of various types. Rows
24 at the top and bottom of a table and columns at the left and right edges of
25 a table can be designated as headers, which means that if the table must be
26 broken across more than one page, those rows or columns are repeated on each
29 A table is not itself an output_item, and thus a table cannot by itself be
30 used for output, but they can be embedded inside struct table_item (see
31 table-item.h) for that purpose. */
36 #include "libpspp/compiler.h"
46 Many table-related declarations use 2-element arrays in place of "x" and "y"
47 variables. This reduces code duplication significantly, because much table
48 code treats rows and columns the same way.
50 A lot of code that uses these enumerations assumes that the two values are 0
51 and 1, so don't change them to other values. */
