HTML 中表格table 的相关知识

<table>标签中比较少见的属性和子标签：

**summary 属性：**用于概括整个表格的内容。它对于搜索引擎的机器人记录信息十分重要。

**bordercolor 属性：**用来设置表格边框的颜色。但它在不同的浏览器下显示的效果不一致。

（不推荐使用bordercolor 属性，而推荐使用CSS 样式表的border 属性来进行设置）

**cellspacing 属性：**用来设置表格的单元格之间的间距。

（推荐使用CSS 样式表的border-collapse 属性来进行设置）

**<caption> 标记：**表示表格的大标题，该标记可以出现在<table> 之间的任意位置。

它对于搜索引擎的机器人记录信息十分重要。

**<th> 标记：**用于表示表格的行或者列的名称。

**<th> 标记的scope 属性**：专门用来区分行名称和列名称。如：<th  scope='row'> 或 <th  scope='col'>

**<table>里还包含：<thead> 、<tbody> 、<tfoot> 标记。**它们分别表示表格的表头，表正文，表脚。 
             在打印网页内容的时候，如果表格很大，一页打印不完，<thead>和<tfoot>将在每一页出现。

（注意：在IE 中无效，但在 Firefox 有效）

经典的表格代码如下：

<table style="table-layout:fixed; word-wrap:break-word; border:0px none; border-collapse:collapse; word-break:break-word; padding:0px; width:699px">

</table>

显示效果如下：

注意：

IE6 只有<a>标记支持:hover 伪类，其余标签都不支持！

并且<a>标记的伪类有顺序：a:link -> a:visited -> a:hover -> a:active

利用DOM 的方法和属性实现对表格的动态操作

A  利用DOM 动态添加一行

B  利用DOM 修改单元格内容

C  利用DOM 删除一个单元格或一行

D  利用DOM 动态添加一列，并动态删除某行

E  利用DOM 动态删除某一列

完毕。

**使用javascript 实现表格数据管理**  
=============================================================  
**详细讲解:** [http://www.cnblogs.com/jaiho/archive/2011/02/20/table\_manager.html][http_www.cnblogs.com_jaiho_archive_2011_02_20_table_manager.html]  
  
**此文使用javascript 实现了表格数据管理的以下几个功能：**  
\--------------------------------------------------------------------------------------------------------------------------  
o 点击添加按钮可以添加一个空的可以修改的记录。  
o 点击表格单元格可以修改文本。  
o 修改后实现了保存的接口。  
o 如果添加了新的记录而未做任何修改值都为null，保存全部时将被忽略。  
o 保存全部时只保存修改过的值，原有的数据不再重复保存。  
o 刷新时如果数据未保存则提示保存。  
o 点击删除时如果是临时添加的无效数据则直接删除，如果保存过的记录则实现了记录删除的接口。  
  
考虑到嵌套的比较多就没有使用form表单，使用javascript 直接解析DOM来分离出了要传递的数据。
