When to use multiple tgroups

You can break a table into multiple tgroup groups.

Typecodes for thead - indicates a new tgroup if used multiple times in a single table

TCH1

Table column head

TCH2

Sub-table column head

TSH

Table spanner head

Where typecodes TCH1, TCH2, or TSH have been used multiple times within a single table, these items represent multiple thead elements within a table, and therefore multiple tgroup elements are needed within a single table.

Where typecodes are not indicated break tables into multiple tgroups in any of the following situations:

  • each chunk of the table has its own heading (not just bold text), and the style of the heading is consistent throughout the table (see example)
  • the number of columns changes from chunk to chunk (see example)
  • the column widths in adjacent chunks changes. (see example)

In all other cases use a single tgroup. This example shows text that is presented in bold but is not a heading.

Sub-topics

  1. Example table with two tgroup elements (columns and widths change)

    The example shows two tgroup groups in a single table.

  2. Example table with multiple thead elements with consistent style

    The example uses multiple tgroup elements and multiple thead elements and demonstrates where tgroups are needed when multiple theads appear with the same style.

  3. Example table with single tgroup element and bold

    The example uses a single tgroup and thead element and contains bold text within that are not representative of heading levels in the table.
