All cells of a QTableWidget that contain data are QTableWidgetItems.

That looks pythonic ;)

for row in myTable.rowCount():
  if myTable.item(row, 0) is not None:
    myTable.item(row, 0).setFlags(Qt.IsSelectable)

Of course this only works if the table is already populated, if you
populate it later on with something like:

myTable.setItem(somerow,somecol, QTableWidgetItem(somestring))

do it in 2 steps instead for the column 0:

item = QTableWidgetItem(somestring)
item.setFlags(Qt.IsSelectable)
myTable.setItem(somerow,somecol,item)

Ah, had no experience with the commercial version yet.

No it doesn't. It has a QTableModel, which can be hooked into a
QTableView. But you'd need a SQL database for this and they'd be
editable too, I think.

If you have a database underlying, maybe you should consider
implementing your own model on top of it and using a plain QTableView to
display the data. That way you don't have to set each individual item to
be non-editable, you could more easily do it for a complete row.

Check the examples that come with PyQt4, there are a couple of custom
models in there. Also with QAbstractTableModel as base you don't have
much more to do than implement flags, data, setData, row und
columnCount.
