Use transform scale(1,1) property with box-shadow it will solve the problem.
tr:hover {
transform: scale(1);
-webkit-transform: scale(1);
-moz-transform: scale(1);
box-shadow: 0px 0px 5px rgba(0,0,0,0.3);
-webkit-box-shadow: 0px 0px 5px rgba(0,0,0,0.3);
-moz-box-shadow: 0px 0px 5px rgba(0,0,0,0.3);
}
