Setting the value of one cell in QTableWidget fills everything.

[Constantly Distracted]

I've just started PyQt programming and I've run into this little
problem. When I set the text of one cell in my table, all the other
cells fill with that value.

All I wanted to do was run a loop, printing in each cell the row and
column number.
Here's the code.

------------------------------

from PyQt4 import QtGui,QtCore
import sys

class mywindow(QtGui.QWidget):
    def __init__(self,parent=None):
        QtGui.QWidget.__init__(self,parent)
        self.resize(700,700)
        self.mytable=QtGui.QTableWidget(7,6,self)
        self.mytable.resize(700,700)

    def filltable(self):
        items=QtGui.QTableWidgetItem()
        for column in range(self.mytable.columnCount()):
            for row in range(self.mytable.rowCount()):
                items.setText("row: " + str(row) + " column: " +
str(column))
                self.mytable.setItem(row,column,items)


app=QtGui.QApplication(sys.argv)
mainwin=mywindow()
mainwin.filltable()
qb.show()
app.exec_()
