用js模仿word格式刷功能实现代码 [推荐]

Format Brush

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;
}

B   
I   
U   
S   
R   
Brush 再次点击Brush以结束使用格式刷

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，

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。
