Adding an action to a Data_table

jmlweb

I'm trying to add an "EDIT" action to a table, generated with the library Data_Table, but I don't understand the example in the user_guide at all...

In this example: "$this->data_table->add_action($field, $action)", what type has $field (int, string, object, array)?

PD: sorry if I'm annoying you with all my asksings

I answer to my own: You must use "$this->data_table->assign_data($table_data)" after adding the actions, not before...
