user table different content table

Hello everybody!!

I'm developing a webpage with drupal 7 and i would like to make a section called 'bills' in this section i would show a table with 4 rows; the first for display links of bills, the second for display the amount to pay, the third to display the state 'paid' or 'pending' and the last one for pay the bill with other link. i would like to change the content of the table to the different users. how can i do that?. how can i do a relationship between the files pdf and the users? i don't know how the OG module can help me...

thank you very much!
