HTML Tables Freeze Panes

Hello 

We have a web application that is fully HTML based. Currently we have a 
feature in Internet Explorer to build a HTML table with a Fixed Header by 
using the below style tag on the TR element. top: 
expression(this.parentElement.parentElement.parentElement.parentElement.scrollTop-3);

Currently, I am unable to locate a parallel feature that would work for 
other browsers. I recommend that we must add a similar feature in the 
specification to say <tbody style="overflow: auto"></tbody> and the table 
body must be allowed to scroll. We must extend this to be available for 
the columns as well. using colgroup. 

The work around we are using is two tables one for the header and one for 
the body of the table contents. Now synchronizing the alignment across 
tables becomes a major issue. 

Any help in this regard is appreciated.
