Controllers and Views

Hi all,
I have two tables: tbl1 and tbl2. Both tables tracks ‘stocks’ that
have been sent and those that have been retrieved for a particular
date. information is stored in a database explained below

tbl1 has fiels id, name, stock, date_retrv (retrv = retrieved),
totl_retrv (totl=total)
tbl2 has fields id, name, stock, date_sent, totl_sent

I want to format an inventory detail to show like this.

Date (Common Date,Literally) | Initial Stock | Retrieved | Sent |
Remaining Cards

2008-08-08                              | 0                  |
10            |5       |  20
2008-08-08                              | 20                |
15            |10     |  25

Remaining = (Initial Stock + Retrieved) - Sent

So now my problem is to be able to use my controller and view to get
this information formatted like the above table into a view page.

Any Suggestions.

Thanks
Yung-Rick :-)
