Re: Newbie question - BTemplate/Directives/Tables

You can try using the Dir::Set_Attr directive.

See the following for understanding how the various directives work...
http://barracudamvc.org/Barracuda/docs/comp/tutorial_hello_world2.html#Understanding_Directives

See HelloWorld2b in the component tutorial for an example...
http://barracudamvc.org/Barracuda/docs/comp/tutorial_hello_world2b.html

Look at the HelloWorld2b2 template where it has...

<table summary="" class="Dir::Set_Attr.HelloWorld.Summary.summary">

The corresponding code fills the "summary" attribute with the data returned 
in the HelloWorld model with the "Summary" key...

in 
http://barracudamvc.org/Barracuda/src/org/enhydra/barracuda/tutorials/comp/HelloWorld2b.java 
...
...
...
else if (key.equals("Summary")) return "Shopping List Table";
...
...

I believe you could also return null so that it wouldn't add a "summary" 
attribute.  However, I haven't tested that.  If that would work, then you 
could selectively set an attribute only when you really need it.
