I realize this is a fairly old post, however I found myself here looking for a solution.
I ended up using a little but of jQuery. ('.column' refers to my :table-cell elements)
jQuery(document).ready(function($){
$('.column').each(function(){
var $this = $( this )
$this.height( $this.height() );
});
});
This forces an explicit height equal to the flowed height causing my elements with 100% height within the .column to actually fit the full width.
Works in current versions of Firefox ,Chrome and IE 9.
Revision: If you are loading images within the table-cell elements which will effect the height then you will want to run the above code on jQuery(window).load() instead.
Chrome has issues with image dimensions at document.ready.
Moving the the above code .load fixed the issue.
.load is called after all elements have loaded vs .ready which can execute before all elements (including images) are loaded
