Right.. Answering my own question in case others find themselves stuck
with the same requirement.
QTableView::setItemDelegate is the solution. That takes a
QAbstractItemDelegate. You should make your own delegate (on top of
QItemDelegate) like so:

CustomDelegate : public QItemDelegate
{
  ...
};

Then you should re-implement the createEditor method with whatever
component you want. In my case i simply make a QLineEdit and set
readOnly to false. That did it for me.
