See the corrected css rule below.

div.tsc_pricingtable03 div.column_1:hover, 
div.tsc_pricingtable03 div.column_2:hover, 
div.tsc_pricingtable03 div.column_3:hover, 
div.tsc_pricingtable03 div.column_4:hover {

position: relative;
z-index: 100;
left: -5px;
top: -15px;
box-shadow: 5px 0px 30px rgba(0, 0, 0, 0.5);
-webkit-box-shadow: 5px 0px 30px rgba(0, 0, 0, 0.5);
-moz-box-shadow: 5px 0px 30px rgba(0, 0, 0, 0.5);
margin-bottom: -30px; /// Note the added removal of the bottom margin that all "non" active elements have
}

This is needed because you are giving the wrapper a 100% height so it will ALWAYS maintain that 24px padding. However, to keep the :hover element from changing the height of the wrapper you need to have that element specifically remove all the padding added by the wrapper to effectively ignore it.
