It's not clear how you are binding the the EventTracker class to the table.I'm assuming you are using a corresponding editor and renderer class and then setting the render and editor like this table.setDefaultRenderer(EventTracker.class,new EventTrackerRender()); and table.setDefaultEditor(EventTracker.class,new EventTrackerEditor());.Editor is used in case only if you need to change the EventTracker bean through the table.

If it done from outside the table (ie.through code) override the setValueAt function in the Table model and then get the EventTracker Object(which is the current object) using getValueAt and make necessary changes (if Eventtracker is mutable object).In case of immutable object make a new object of EventTracker and set it to the object array.After this you should either call fireTableDataChanged() which is going to repaint the whole table or call fireTableCellUpdated(row,col) for a particular cell to be rendered again.
