<?tbcpref>

This command assigns an existing cell paragraph reference to individual cells in a table. If the command is inserted at the top of the table every paragraph in the table will reflect the specified style. A table paragraph style allocated in this way can be overridden at individual cell level, however: a second <?tbcpref> command or a normal style tag applied in the cell itself will supersede the table style. Alternatively, use <?tbcolpref> to specify the reference on a per column basis and then override this with individual <?tbcpref> commands.

Since the cell paragraph reference occurs before a paragraph style, normal attributes in the cell paragraph reference can be overridden by a subsequent style tag. This does mean though that attributes in the lump will not be affected.
