html table表格斜线表头的实现方法总汇

1、UI背景图实现

2、 css3中transform属性

3、利用border-top和border-left

table {  
    border-collapse: collapse;  
    border: 1px #eee solid;  
    width: 80%;  
    min-width: 300px;
    margin: 0 auto;    
}  
th{  
    border: 1px solid #ddd;  
    text-align: center;  
    height: 100px;
}  
.th_head{/*宽高100px,100px*/
	width:200px;
	position: relative; 
}  
.box{  
    border-top: 100px #ff0 solid;  /*上边框宽度等于表格第一行行高*/  
    border-left: 200px #0ff solid;  /*左边框宽度等于表格第一行第一格宽度*/  
}  
.a,.b{
	font-style: normal;  
    display: block;  
    position: absolute;  
    width: 200px;
    height: 50px;
    line-height: 50px;
}
.a{
    top: 0px;  left: 0px;   
}  
.b{   
    top: 50px;  left: 0px;     
}  
</style>

<table>  
    <tr>  
        <th class="th_head">  
            <div class="box">  
                <em class="a">A</em>
                <em class="b">B</em>  
            </div>  
        </th>  
        <th>C</th>    
    </tr>   
</table>

4、css3的canvas

5、js的实现

<TABLE border=0 bgcolor="000000" cellspacing="1" width=400  
        style="margin-left: 100px;">  
        <TR bgcolor="FFFFFF">  
            <TD width="111" height="52"><table width="100%" height="100%"  
                    border="0" cellpadding="0" cellspacing="0">  
                    <tr>  
                        <td id="td1"></td>  
                        <td>成绩</td>  
                    </tr>  
                    <tr>  
                        <td>姓名</td>  
                        <td id="td2"></td>  
                    </tr>  
                </table></TD>  
            <TD width="81">数学</TD>  
            <TD width="96">英语</TD>  
            <TD width="99">C语言</TD>  
        </TR>  
        <TR bgcolor="FFFFFF">  
            <TD>张三</TD>  
            <TD>55</TD>  
            <TD>66</TD>  
            <TD>77</TD>  
        </TR>  
        <TR bgcolor="FFFFFF">  
            <TD>李四</TD>  
            <TD>99</TD>  
            <TD>68</TD>  
            <TD>71</TD>  
        </TR>  
        <TR bgcolor="FFFFFF">  
            <TD>王五</TD>  
            <TD>33</TD>  
            <TD>44</TD>  
            <TD>55</TD>  
        </TR>  
    </TABLE>  
    <script type="text/javascript">
