STRUCTURE TYPE     DESCRIPTION

LBody              (List body) The descriptive content of a list item. In a dictionary list, for example, it con-
                   tains the definition of the term. It can either contain the content directly or have other
                   BLSEs, perhaps including nested lists, as children.


         Table Elements

         The structure types described in Table 10.24 are used for organizing the content
         of tables.

         Note: Strictly speaking, the Table element is a BLSE; the others in this table are nei-
         ther BLSEs or ILSEs.

                       TABLE 10.24 Standard structure types for table elements
STRUCTURE TYPE     DESCRIPTION

Table              (Table) A two-dimensional layout of rectangular data cells, possibly having a complex sub-
                   structure. It contains either one or more table rows (structure type TR; see below) as chil-
                   dren; or an optional table head (structure type THead; see below) followed by one or more
                   table body elements (structure type TBody ; see below) and an optional table footer (struc-
                   ture type TFoot; see below). In addition, a table may have an optional caption (structure
                   type Caption; see “Grouping Elements” on page 899) as its first or last child.

TR                 (Table row) A row of headings or data in a table. It may contain table header cells and table
                   data cells (structure types TH and TD; see below).

TH                 (Table header cell) A table cell containing header text describing one or more rows or col-
                   umns of the table.

TD                 (Table data cell) A table cell containing data that is part of the table’s content.

THead              (Table header row group; PDF 1.5) A group of rows that constitute the header of a table. If
                   the table is split across multiple pages, these rows may be redrawn at the top of each table
                   fragment (although there is only one THead element).

TBody              (Table body row group; PDF 1.5) A group of rows that constitute the main body portion of
                   a table. If the table is split across multiple pages, the body area may be broken apart on a
                   row boundary. A table may have multiple TBody elements to allow for the drawing of a
                   border or background for a set of rows.
                   Note: (Table footer row group; PDF 1.5) A group of rows that constitute the footer of a ta-
TFoot
                   ble. If the table is split across multiple pages, these rows may be redrawn at the bottom of
                   each table fragment (although there is only one TFoot element.)
