[Zope] How to format database query?

Hello there, I make a query in postgresql with: select * from table_name and i put it in html with: <dtml-in wet_query> <b> <dtml-var field1>.</b> <dtml-var field2> </dtml-in> field1 is a char field and field2 is a text field (column) How can i format this output? Is it possible in dtml or python? I think it must be possible with somekind of string manipulation but is don't know how to inplement it. Thanks for any help.
