鼠标经过改变表格背景属性 
This tutorial will teach you how to make a menu like tables that will change background color when you mouseOver.
这份教程将教会你下面的技巧：当鼠标移至表格（单元格）上方时，改变表格的背景颜色。
1. First create your menu on your page. Then identify your two colors, one is for mouseOver and another one for initial color. In my case mouseOver color is: #999999 and initial color is: #CCCCCC
首先，在你的页面上创建一个菜单；然后，创建两种用于鉴别的颜色体：一个是表格的初始颜色，另一个是鼠标移至表格上方时所产生的背景颜色。在我这个案例中，我所默认使用的背景效果颜色（鼠标以上去时）是：#999999，初始颜色是：#CCCCCC。
2. Now copy this code to the head of you document. (Between <HEAD></HEAD> tags)
现在，将下面这段代码复制到文档头部。（位于<HEAD></HEAD>标签之间）
|
<style type="text/css"> |
Change the color in blue with your own colors.
将蓝色改变为你所需要的颜色。
td.off will be our initial table color which is lighter gray #CCCCCC.
td.off意指表格的初始颜色，这里设置的初始值是#CCCCCC。
td.on will be our changing color which is darger gray #999999.
td.on意指鼠标移动至表格上方时显示的颜色，这里设置的值是深灰色（#CCCCCC）。
3. Now we have to apply the CSS to the table that you have created. Insert the following code in every <td> tag inside your table. class="off" onmouseover="this.className='on'" onmouseout="this.className='off'"
现在，我们需要做的是将这段CSS代码应用到已经创建的表格中。将下面这段代码插到表格中的每个<td>标签中。“ class="off" onmouseover="this.className='on'" onmouseout="this.className='off'" ”
So your code should look like this:
加入后的代码如下所示：
|
<td class="off" onmouseover="this.className='on'" onmouseout="this.className='off'">MENU 1</td>
|
Let's go through the code one by one:
让我们逐行理解下面的这段代码：
1: <td class="off" - Assigns the off class of our CSS to the table column, which means initially the table column background will have a color of #CCCCCC
<td class="off" —— 为表格中的每列单元格所对应的CSS的off类赋值，它的意思是：表格每列单元格的初始颜色是：#CCCCCC。
2: onmouseover="this.className='on'" - Assigns the on class of our CSS to the table column, when we mouseOver on it
onmouseover="this.className='on'" ——当鼠标移至表格中的每列单元格之上时，所对应的CSS的效果。
3: onmouseout="this.className='off'"> - Assigns the off class of our CSS to the table column back, when we take away the mouse from it.
onmouseout="this.className='off'"> ——当鼠标从表格中的每列单元格上移开时，所对应的CSS的效果。
4. Full Code
上图示例所对应的全部代码如下：
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<title>Table Background Change</title>
<style type="text/css">
td.off {

}

</head>
<body>

<td class="off" onmouseover="this.className='on'"
onmouseout="this.className='off'"><font color="#000000" size="1">Menu

</tr>
<tr>
<td class="off" onmouseover="this.className='on'"
onmouseout="this.className='off'"><font color="#000000" size="1">Menu

<tr>
<td class="off" onmouseover="this.className='on'"
onmouseout="this.className='off'"><font color="#000000" size="1">Menu
