But I need to export the data of another user using my
login id. And also I need to exclude few tables. In that
case I have to use both owner and tables parameter.

Can anyone suggest a solution to this

You just have to specify the owner before the table name.

eg:
exp userid=myuser file=exp.dmp tables=(owner1.tablename1,owner2.tablename2)
