I have an alternative HTML library if you are interested... it uses an intermediate representation (a DOM style model) and defines the type ShowDOM = DOM -> DOM , allowing efficent concatination using function composition, finally a layer on top of this using the type ShowDOM -> (a,ShowDOM), instanciating a Monad allows monadic composition of html pages - there is also some static type checking done by creating the types: newtype HtmlFragment = HtmlFragment (ShowDOM -> (a,ShowDOM)) newtype HtmlTableFragment = HtmlTableFragment (ShowDOM -> (a,ShowDOM)) etc... this allows you to compose HTML as in the following example attrTable [MkAttribute ("cellspacing","0")] ( do htmlTR (attrTD [MkAttribute ("colspan","2")] $ htmlText "Test Cell 1")) htmlTR ( do htmlTD (htmlText "Cell 2 (Left)") htmlTD (htmlText "Cell 3 (Right)"))) If you (or anyone) are interested let me know ...

Can someone explain the reasoning behind using a function to describe a Table rather than just a list of lists?

Just my feeling, but perhaps it is essentially the same reason why ShowS is String -> String rather than String, so that concatenation becomes efficient? _______________________________________________ Glasgow-haskell-users mailing list Glasgow-haskell-users@haskell.org http://www.haskell.org/mailman/listinfo/glasgow-haskell-users
