推荐一篇利用th,colgroup,col定义表格样式

定义表格各列的样式，不用每个td都在那里加一堆的Class，利用th,colgroup,col等属性，轻松搞定^_^
代码如下：

<style> 
table.Demo { 
  border-collapse: collapse; 
  color: #454545; 
  font: 11px/150% Verdana, Arial, Helvetica, sans-serif; 
} 
table.Demo th { 
  padding: 3px 7px; 
  border: 1px solid #f60; 
  border-width: 2px 1px 1px; 
  background: #ffffe1; 
} 
table.Demo td { 
  padding: 3px 7px; 
  border: 1px solid #f60; 
} 
table.Demo col.Col1 { 
  text-align: right; 
  background: #f5f5f5; 
} 
table.Demo col.Col2 { 
  color: #00c; 
} 
table.Demo col.Col3 { 
  font-style: italic; 
} 
</style> 
<table class="Demo"> 
  <tr> 
    <th>TagName</th> 
    <th>ClassName</th> 
    <th>CSS</th> 
  </tr> 
  <colgroup> 
    <col class="Col1" /> 
    <col class="Col2" /> 
    <col class="Col3" /> 
  </colgroup> 
  <tr> 
    <td>table</td> 
    <td>Demo</td> 
    <td>border-collapse: collapse;<br />color: #454545;<br />font: 11px/150% Verdana, Arial, Helvetica, sans-serif;</td> 
  </tr> 
  <tr> 
    <td>th</td> 
    <td></td> 
    <td>padding: 3px 7px;<br />border: 1px solid #f60;<br />border-width: 2px 1px 1px;<br />background: #ffffe1;</td>  
  </tr> 
  <tr> 
    <td>td</td> 
    <td></td> 
    <td>padding: 3px 7px;<br />border: 1px solid #f60;</td> 
  </tr> 
  <tr> 
    <td>col</td> 
    <td>Col1</td> 
    <td>text-align: right;<br />background: #f5f5f5;</td> 
  </tr> 
  <tr> 
    <td>col</td> 
    <td>Col2</td> 
    <td>color: #00c;</td> 
  </tr> 
  <tr> 
    <td>col</td> 
    <td>Col3</td> 
    <td>font-style: italic;</td> 
  </tr> 
</table>
