[web2py] How to insert icons into a column of a table created using SQLTABLE()

[Valter Foresto]

I'm using SQLTABLE() into a controller to generate a table for the next 
view. 

A column of the table report only few states (text) that can might be better 
represented using small, 16x16 or 32x32, images.
It is possible to insert icons, instead of text, into a table column and 
then pass the result to the viewer ?  

Thanks in advance for suggestions.
