Difference between web controls rendering and html table properties using ASP.NET - css

Question

I'm designing a website in ASP.NET and I want to build table with some text, textboxes and validators in it. The problem is that table looks different in Firefox and IE. Here is an example:

Here is the table code in ASP.NET:
<table align="center" cellpadding="0" cellspacing="1" style="text-align: right; border-collapse: separate;">
<tr>
<td>
Nadawca:
</td>
<td>
<asp:TextBox ID="TextBoxNadawca" runat="server" Width="250px" BorderStyle="none"
BackColor="#c1ae85"></asp:TextBox>
</td>
<td align="left">
<asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ErrorMessage="Nadawca jest wymagany."
ControlToValidate="TextBoxNadawca" ForeColor="Red"></asp:RequiredFieldValidator>
</td>
</tr>
<tr>
<td>
Adres e-mail:
</td>
<td>
<asp:TextBox ID="TextBoxMail" runat="server" Width="250px" BorderStyle="none" BackColor="#c1ae85"></asp:TextBox>
</td>
<td align="left">
<asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="E-mail jest wymagany."
ControlToValidate="TextBoxMail" ForeColor="Red"></asp:RequiredFieldValidator>
<asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server" ControlToValidate="TextBoxMail"
ErrorMessage="Nieprawidłowy format." ForeColor="Red" Style="position: absolute;
top: 589px; left: 632px; width: 160px;" ValidationExpression="\w+([-+.']\w+)*#\w+([-.]\w+)*\.\w+([-.]\w+)*"></asp:RegularExpressionValidator>
</td>
</tr>
<tr>

Answer 1

When i remove your styling code
<table align="center" cellpadding="0" cellspacing="1" style="text-align: right; border-collapse: separate;">
to
<table align="center">
It shows same for IE, Firefox and Chrome. So if you want to style your table ill suggest you to try CSS

Answer 2

Don't use tables for your layout, use CSS. The only time you should use tables is for tabular data. By using CSS here you can omit border-bottom where you are getting the double borders.
