Visual Studio模块创建dotnetnuke的项目之间的原因无法解释

Question

I created a linqdatasource connection to my sql server and i load my data inside a listview. Now for that listview i added another table from the top of that listview like a title.(i also tried div or p)

The issue now is when i add this module to my website there is a gap between the listview and the top item whether its a table or a dive or anything.

Inside visual studio it show fine with no gap. Here is my code:

<%@ Control Language="VB" ClassName="MyModules.ProductDetailsModule" Inherits="DotNetNuke.Entities.Modules.PortalModuleBase" %>
<%@ Import Namespace="CodingStaff.Modules.MenuBox.Licensing" %>

<script runat="server">
    Dim prodID As Integer
</script>

<%
    prodID = Convert.ToInt32(Request.QueryString("ProductID"))
%>

<style type="text/css">
    h1 {
        font-family: Lucida Grande;
        font-size: 15px;
    }

    td {
        font-family: Lucida Grande;
        font-size: 13px;
        color: #999999;
    }
</style>

<table style="width: 704px;">
    <tr style="width: 704px;">
        <td>
            <table>
                <tbody>
                    <tr bgcolor="#e7e7e5" height="35">
                        <td align="left" style="width: 704px;">
                            <h1 style="color: #666666;">Technical info</h1>
                        </td>
                    </tr>
                </tbody>
            </table>
        </td>
    </tr>
    <tr>
        <td>
            <asp:ListView ID="ListView1" runat="server" DataKeyNames="PRODUCTID" DataSourceID="LinqDataSource1">
                <ItemTemplate>
                    <tr>
                        <td runat="server" style="width:352px"><strong>Product Code:</strong></td>
                        <td style="width:352px"><strong>
                            <asp:Label ID="PRODUCTIDLabel" runat="server" Text='<%# Eval("PRODUCTID") %>' /></strong>
                        </td>
                    </tr>
                    <tr>
                        <td runat="server" style="width:352px"><strong>Name:</strong></td>
                        <td style="width:352px"><strong>
                                <asp:Label ID="PRODUCTNAMELabel" runat="server" Text='<%# Eval("PRODUCTNAME") %>' /></strong>
                        </td>
                    </tr>
                    <tr>
                        <td runat="server" style="width:352px"><strong>Description:</strong></td>
                        <td style="width:352px"><strong>

                    </tr>
                </ItemTemplate>
                <LayoutTemplate>
                    <table runat="server" border="0" style="">
                        <tr runat="server" id="itemPlaceholderContainer">

                        </tr>
                    </table>
                    <div style="">
                    </div>
                </LayoutTemplate>
            </asp:ListView>
        </td>
    </tr>
</table>

<asp:LinqDataSource ID="LinqDataSource1" runat="server" ContextTypeName="ProductsModule.ProductsModuleDALDataContext" EntityTypeName="" TableName="PRODUCTs" Where="PRODUCTID==@prodID">

And here a similar code with the same issue:

<%@ Control Language="VB" AutoEventWireup="false" CodeFile="View.ascx.vb" Inherits="DesktopModules_MyModules_ProductsModule_View" %>
<asp:LinqDataSource ID="LinqDataSourceProducts" runat="server" ContextTypeName="ProductsModule.ProductsModuleDALDataContext" EntityTypeName=""
     TableName="PRODUCTs" OrderBy="PRODUCTNAME" Select="new (PRODUCTID, PRODUCTNAME)">
</asp:LinqDataSource>

    font-family:Lucida Grande;
    color:#666666;
    font-size:15px;
    }
    table{
    margin-top: 10px;
    }
     A{
    text-decoration:none;
    }
    a:link{
    color:#666666;
    }
    a:visited{
    color:#666666;
    }
    a:hover{
    color:#666666;
    }
    a:focus{
    color:#666666;
    }
    a:active{

    }
</style>

UPDATE!!!!!

Ive looked the website from chrome with f12 to see what happens with the gap. Ive notice that on every table declaration a gap is added. here is a sample image. the orange is the gap thats generated and also below Technical info there is a gap again.

Answer 1

I found the problem to this. I had inside another module in another page a padding top 30px. And as it seems it shares this options to the whole site. So anywhere that a table declaration existed it added a 30px gap on top. I fixed it by making that specific 30px padding with table.aVariableName so that is dinstinct to a specific table only
