步骤：
1：在单选按钮组控件中 添加属性 RepeatLayout ,其值选“flow”<asp:RadioButtonList ID="rblcellstat" runat="server" Width="240px" RepeatDirection="Horizontal" RepeatLayout="flow">
(说明：选“flow”，RadioButtonList控件在网页中显示为<span></span>形式，若选“table”，在网页中显示<table><tr><td></td></tr></table>形式的html代码)
2：在css文件中写样式
span.includerbl input{text-align:center;border: 0px 0px 0px 0px} /* by djh */
3：引用样式文件<link href="http://www.cnblogs.com/include/main05.css" type="text/css" rel="stylesheet" />
自动启用
选RepeatLayout="flow" 时，网页源代码样文如下：
<table cellpadding="0" cellspacing="0" width="100%" class="outer"> <tr> <td style="text-align:right">設定格子狀態：</td> <td style="width:260px"> <span id="rblcellstat" style="display:inline-block;width:240px;"><input id="rblcellstat_0" type="radio" name="rblcellstat" value="1" checked="checked" /><label for="rblcellstat_0">正常</label><input id="rblcellstat_1" type="radio" name="rblcellstat" value="2" /><label for="rblcellstat_1">滿格</label><input id="rblcellstat_2" type="radio" name="rblcellstat" value="3" /><label for="rblcellstat_2">停用</label><input id="rblcellstat_3" type="radio" name="rblcellstat" value="4" /><label for="rblcellstat_3">抽盤</label></span></td> <td><input type="submit" name="btnSet" value="設定" id="btnSet" style="width:80px;" /></td> </tr> </table>
选RepeatLayout="table" 时，样文如下：
<table cellpadding="0" cellspacing="0" width="100%" class="outer">
<tr><td style="text-align:right">设定格子状态：</td>
<td class="includerbl" style="width:260px">
<table id="rblcellstat" border="0" style="width:240px;">
<tr><td><input id="rblcellstat_0" type="radio" name="rblcellstat" value="1" checked="checked" /><label for="rblcellstat_0">正常</label></td>
<td><input id="rblcellstat_1" type="radio" name="rblcellstat" value="2" /><label for="rblcellstat_1">满格</label></td>
<td><input id="rblcellstat_2" type="radio" name="rblcellstat" value="3" /><label for="rblcellstat_2">停用</label></td>
</tr></table>
</td>
</tr>
