enabling audit trail on a table

dear sir / madam

we have the audit trail already set up on our pd910 environment and enabled on certain number of tables

the management asks me to add one more table to the audit trail but i have never worked with audit trail

i read the document but it is still not clear

can anyone help me how can i add a table to the audit trail for example f0101

what are the steps to add it to the audit trail knowing that the setup is there i dont need to set it up i just need to add a table to the audit
