I do not think you can do it in CSS, but you can calculate a pixel perfect width with javascript. Let's say you use jQuery:

HTML code:

JS Code:

$(function(){
   var total = $("#container").width();
   $("#col1").css({width: Math.round(total/3)+"px"});
   $("#col2").css({width: Math.round(total/3)+"px"});
   $("#col3").css({width: Math.round(total/3)+"px"});
});
