[PyQt] Large Table Example in PyQt4

I am fairly new to python and programming as a whole and would like to develop a small application capable of plotting simple 2D graphs and also display such data in a table.  In my initial assessment of PyQt4 I have been able to load my data into a table but it is terribly slow.  I am using a QAbstractTableModel example that I found on the web:

http://iwiwdsmi.blogspot.com/2007/12/pyqt-43-qtableview-qabstracttable-model.html

This has been useful but if I load a large numpy array (5 x 250,000) into this example it is insanely slow.  It seems as though there was a "bigtable.py" example for PyQt3 but I cannot seem to port this to version 4.  The Qt website also discusses the use of large tables when programming C++ but this is out of my league.  Does anyone have a simple solution to this problem or perhaps a quick example that I can insert a numpy array into?  Again, I'm pretty new to python but am eager to learn.  

Cheers,

Brian
