You can assign group names to tables, and then apply properties to all tables in the group with a single setting. Each table can belong to one table group. You can create table groups two ways:
Create table groups in the configuration file
Create table groups with configuration PI markers.

To create table groups and assign tables to groups in the configuration file:
[TableGroup] ; TableID = group name used in other Table sections for ID ; the filter first looks for TableID, then group TableID = tablegroupname

Another way to To create a table group, or assign tables to existing table groups, is to insert configuration PI markers in the tables in your DITA document, with content as follows:
[TableGroup]=tablegroupname
