Yes, I'll do that. I'll just wait for this first round of comments and then add that in to the release.
update
Acutally I am thinking it should be available as a hook in the Perl script but also as something that can be specified from the JavaScript end - e.g. add two optional arrays to the config in the HTML page for pre_column_txt and post_column_txt. E.g. if you want red around column two:
var pre_column_txt = new Array(undef,'<span style="color:red">');
var post_column_text = new Array(undef,'</span>');
How's that sound?

Oh, I remember how it sounds :-). It sounds like an easy way to send cross-site scripting attacks. :-) Maybe I'll only do a hook after all. :-)
