RDLC報表控件reportview顯示問題（高度自適應）

代碼：

<table style="background-color: ; overflow: hidden; height:100%;  width: 100%; vertical-align:top;">
             <tr style="">
                 <td style="height: 100%;">
                 </td>
                 <td>
                      <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana"
    Font-Size="8pt" InteractiveDeviceInfos="(集合)" WaitMessageFont-Names="Verdana"
    WaitMessageFont-Size="14pt" style="width:100%; overflow:hidden;">
    <LocalReport ReportPath="D:\wwwroot\reportNew\RDLC\rdlc_temple\rdlc.rdlc">
    </LocalReport>
    </rsweb:ReportViewer>                

</td>
             </tr>
         </table>

顯示問題：在ff和IE8下，會在報表上部顯示一片空白區域，影響美觀，如圖：

解決辦法：

1、去掉紅色字體的style設置，即 height:100%;

<table style="background-color: ; overflow: hidden; height:100%;  width: 100%; vertical-align:top;">
             <tr style="">
                 <td style="height: 100%;">
                 </td>
                 <td>
                      <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana"
    Font-Size="8pt" InteractiveDeviceInfos="(集合)" WaitMessageFont-Names="Verdana"
    WaitMessageFont-Size="14pt" style="width:100%; overflow:hidden;">
    <LocalReport ReportPath="D:\wwwroot\reportNew\RDLC\rdlc_temple\rdlc.rdlc">
    </LocalReport>
    </rsweb:ReportViewer>                

</td>
             </tr>
         </table>

2、直接使用div作為容器

 <div id="mainPanel" style="background-color: ; border-left:1px solid scrollbar; overflow: hidden; height: 100%;">
        <rsweb:ReportViewer ID="ReportViewer1" runat="server" Font-Names="Verdana"
    Font-Size="8pt" InteractiveDeviceInfos="(集合)" WaitMessageFont-Names="Verdana"
    WaitMessageFont-Size="14pt" style="width:100%; overflow:hidden;">
    <LocalReport ReportPath="D:\wwwroot\reportNew\RDLC\rdlc_temple\rdlc.rdlc">
    </LocalReport>
    </rsweb:ReportViewer>    

</div>
