Hi,

I'm badly in need of a datatable with fixed headers and a scrolling body, of 
the type that a few other (some commercial) JSF component sets have.  I was 
digging into the source of the table renderer, and saw a lot of code related to 
scrolling.  It seems that if "height" is available from the CoreTable 
component, the renderer will try to render the body as scrolling.

The <tr:table> tag doesn't expose "height", so you can't do this out of the 
box, but as a test, I quickly created a custom renderer based off the 
default--which basically does everything the same except that it forces 
"height" to have a value.  Sure enough, when I wire this renderer to a custom 
component and display, I get the regular <tr:table> with fixed headers and a 
vertical scrollbar for the body.

In IE. :-(        

There is a bunch of branching in the code to deal specifically with IE (the 
fixed row is rendered with absolute positioning to get around the browser bug), 
but unfortunately nothing in the code that makes other browsers display a 
scrolling body.  That should be the easy part- setting the proper CSS on 
<tbody> ought to do it in Firefox and others.

So my question is, what is the state of this feature?  Hidden, 
half-implemented, or something else?  Any plans to revive it?  (note:  I am 
working off a fairly old build of the 1.2 branch, but I don't recall seeing any 
updates about this)  For my purposes, I was going to either (a) let the IE hack 
run in all situations- not ideal but might work okay, or (b) continue extending 
the table renderer to properly write CSS for non-IE browsers in scrolling 
situations.  Any insights would be appreciated.

Thanks in advance,
Rogers
