There are couple of ways to do this, but the simplest would be to add a textbox for search values and a button. Give the button a dynamic action triggering on click which refreshes the tabular form region. Then, in the region definition for the tabular form, where you get a sql expression for what rows to return, put in a where clause that filters based on the value in the search box.
This won't get you quite to interactive reports, but it's a step up. To my knowledge there is not a way (without essentially rewriting interactive reports) to get that flexibility of reporting with the ability to do inline editing.
