Unexplained gap between items for visual studio module creation dotnetnuke - html

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>
<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">
<td runat="server" id="itemPlaceholder"></td>
</tr>
</table>
<div style="">

</LayoutTemplate>
</asp:ListView>
</td>
</tr>

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

And here a similar code with the same issue:

<asp:LinqDataSource ID="LinqDataSourceProducts" runat="server" ContextTypeName="ProductsModule.ProductsModuleDALDataContext" EntityTypeName=""

</asp:LinqDataSource>
<style type="text/css">

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
