I've run into the same issue. You may not realize it, but each cell also has a blank icon. I've gone chasing through the documentation and gotten nowhere. You have re-implemented data() -- you will find that returning None for roles 1 and 10 (icon and check state, respectively) eliminate the display of the checkbox and the empty space for the non-existent icon. If you use something like QSqlRelationalTableModel for the model those roles seem to already be handled, but if you are subclassing you must deal with them yourself. I find some aspects of Qt's model/view/delegate counterintuitive and I am a complete noob, but as far as I can tell the appropriate place to handle this problem -- when subclassing QAbstractTableModel at any rate -- is in the implementation of data(). If that is indeed the case it would be nice for it to be documented. The PySide docs say you must implement rowCount(), columnCount() and data() -- but it doesn't give any hint as to what the implementation of data() might need to handle. Just a brief statement that an implementation of data() must account for each of the roles (with a link to the page enumerating them) would be helpful for those unfamiliar with Qt.
