Calculating Total Height Including Padding Inside DIVs

I found this useful script for setting equal column height for divs. But is doesn't account for the padding inside the divs. How to make it calculate the total height including the padding from the heighest column?

Code:
$('#leftcolumn, #content').equalizeHeights();
(function($){
$.fn.equalizeHeights = function(){
return this.height(
Math.max.apply(this,
$(this).map(function(i,e){
return $(e).height()
}).get()
))}
})(jQuery);
