Maybe CellTable.addCellPreviewHandler will help you.
The event passed to the handler will contain the column index
(CellPreviewEvent.getColumn), as well as the context
(CellPreviewEvent.getContext). From the context you can extract the key
that identifies the row (Context.getKey).
To restrict the event just to mouseover events, do a check inside the
handler for:
event.getNativeEvent().getType().equals("mouseover");
