You can use configuration PI markers and configuration-variable assignments to override settings in the HTML [Table*] sections listed in Table 42-5.
A temporary override to a table affects the entire table within which a configuration PI marker is placed; or the next table, if the PI marker is not in a table.
A persistent override affects the next table with the ID or table format, or in the table group, named by the Key in [Section]Key=Value; or the current instance, if the PI marker is placed in a matching table. For table formats and groups, the override also affects all subsequent matching instances in the same DITA file, unless changed again by a later override.
