Try to switch your selection models: use the MultiSelectionModel as the CellTable's selection model, so that the checkboxes work as expected (with both dependsOnSelection and handlesSelection set to true), and for the master-detail feature, use a CellPreviewEvent.Handler (or DefaultSelectionEventManager#createCustomManager), and RowStyles and getRowElement+addStyleName/removeStyleName for rendering (RowStyles when the CellTable renders the rows, then getRowElement to dynamically update styling).
