broken across more than one page, those rows or columns are repeated on each

- Every table is an instance of a particular table class that is responsible
- for keeping track of cell data. By far the most common table class is
- struct tab_table (see output/tab.h). This header also declares some other
- kinds of table classes, near the end of the file.
-
A table is not itself an output_item, and thus a table cannot by itself be
used for output, but they can be embedded inside struct table_item (see
table-item.h) for that purpose. */
