运行代码

(PS：如果你要拷贝代码下去测试，不要直接拷贝下面的代码，下面的代码在显示的时候被csdn蹂躏了。点击运行代码,然后查看原代码)

<html>
<head>
<title>Format Brush</title>
</head>
<style>
table{
border: solid #ccc 1px;

}
td{
border: solid #ccc 1px;
width: 140px;
height: 25px;
}
.selected{
border: solid red 1px;
}
a{
text-decoration: none;
color: black;
font-weight: bold;
}
.b{
}
.i{
font-style: italic;
}
.u{
text-decoration: underline;
}
.s{
text-decoration: line-through;
}
.r{
color: red;
}
</style>
<body>
<div>
<a href="javascript:setBold();" class='b'>B</a>   
<a href="javascript:setItalic();" class="i">I</a>   
<a href="javascript:setUnderline();" class="u">U</a>   
<a href="javascript:setLineThrough();" class="s">S</a>   
<a href="javascript:setRedColor();" class="r">R</a>   
<a href="javascript:doBrush(this);" class="">Brush</a> <span id="tip" style="display: none;">再次点击Brush以结束使用格式刷</span>
</div>
<table id='t' cellpadding='0' cellspacing='0' border='1'>
<tr><td  class="selected">column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
<tr><td>column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
<tr><td>column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
<tr><td>column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
<tr><td>column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
<tr><td>column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
<tr><td>column1</td><td>column2</td><td>column3</td><td>column4</td></tr>
</table>
<br>
用法：上下左右键移动单元格， 点格式化按扭格式化当前单元格， <br>
点Brush准备使用格式刷，然后点任意单元格就会把当前单元格格式拷贝到被点击的单元格。
