<div>
1、添加引用 

<div style="width: 900px" class="cnblogs_code">
<div><span style="color: rgb(0,0,255)">using</span><span style="color: rgb(0,0,0)"> System.Drawing;
</span><span style="color: rgb(0,0,255)">using</span><span style="color: rgb(0,0,0)"> System.ComponentModel;</span></div>
</div>
2、自定义DataGridViewcolumn
<div style="width: 900px" class="cnblogs_code">
<div><span style="color: rgb(128,128,128)">///</span><span style="color: rgb(0,128,0)"> </span><span style="color: rgb(128,128,128)"><summary></span><span style="color: rgb(0,128,0)">
</span><span style="color: rgb(128,128,128)">///</span><span style="color: rgb(0,128,0)"> 带进度列。单元格内容格式为：值/总值 Eric
</span><span style="color: rgb(128,128,128)">///</span><span style="color: rgb(0,128,0)"> </span><span style="color: rgb(128,128,128)"></summary></span><span style="color: rgb(128,128,128)">
</span><span style="color: rgb(0,0,0)">[Description(</span><span style="color: rgb(128,0,0)">"</span><span style="color: rgb(128,0,0)">带进度列。单元格内容格式为：值/总值</span><span style="color: rgb(128,0,0)">"</span><span style="color: rgb(0,0,0)">)]
</span><span style="color: rgb(0,0,255)">public</span><span style="color: rgb(0,0,0)"> </span><span style="color: rgb(0,0,255)">class</span><span style="color: rgb(0,0,0)"> DataGridViewProcessColumn : DataGridViewColumn
{
</span><span style="color: rgb(0,0,255)">public</span><span style="color: rgb(0,0,0)"> DataGridViewProcessColumn()
: </span><span style="color: rgb(0,0,255)">base</span><span style="color: rgb(0,0,0)">(</span><span style="color: rgb(0,0,255)">new</span><span style="color: rgb(0,0,0)"> DataGridViewProcessCell())
{
}
}</span></div>
</div>

3、自定义DataGridViewCell
<div style="width: 900px" class="cnblogs_code">

运行：如果某Cell的value为：1/20。则我们看到结果将会与图中最后一条结果相同。
