以下是引用片段：
<script type="text/javascript">

var act;
function over(s,nMax){
  var obj=document.getElementById(s);
  var h = parseInt(obj.offsetHeight);
  if (h < nMax){
    obj.style.height = (h + 2)+"px";
    clearTimeout(act);
    act = setTimeout("over('"+s+"',"+nMax+")", 10);
  }
}
function out(s,nMin){
  var obj=document.getElementById(s);
  var h = parseInt(obj.offsetHeight);
  if (h > nMin){
    obj.style.height = (h - 2)+"px";
    clearTimeout(act);
    act = setTimeout("out('"+s+"',"+nMin+")", 10);
  }
}
</script>
<div id="mytd" onmouseover="over('mytd',200);" onmouseout="out('mytd',30);" style="background:#eee;">代码实例：层的滑动展开/折叠</div>

无忧网友 fangxiao9159 再次优化后：

以下是引用片段：
<script type="text/javascript">
var intervalId = null;
function move(id,state){
  var obj = document.getElementById(id);
  if(intervalId != null)
    window.clearInterval(intervalId);
  function change(){
   var h = parseInt(obj.offsetHeight);
   obj.style.height = (state == "down") ? (h + 2) : (h - 2);
  }
  intervalId = window.setInterval(change,10);
}
</script>
<table border="1" cellpadding="0" cellspacing="0" id="mytd" onmouseover="move('mytd','down');" onmouseout="move('mytd','out');">
