how to read data from table after being built?

woodstown

My Table should look something like that:

.-------------------------------------.
| Basket |
+----+-----------------------+-------+
| Id | Name .............. | Price |
+----+----------------------+-------+
| 1 | Dummy product 1 | 24.4 |
| 2 | Dummy product 2 | 21.2 |
| 3 | Dummy product 3 | 12.3 |
+----+----------------------+-------+
| | Total ................. | 57.9 |
'----+------------------------+-------'

I want to calculate the "Total" in the last row depending on what the table is currently displaying.
E.g. the user search in the global search field for "Dummy product 2" -
The total should be 21,2 because only the second row would be displayed.

Therefore i need to go through the currently displayed data in the table and read the data, calculate and put it in the last row.
i need to go through that function every time the table changes. e.g. search, next page, rows per page are changed etc.

Would appreciate your help very much! Thank you.

I've used the footer callback example to add column totals.
The example can be seen here:
