You can use HTML Table inside ItemTemplate. Check this example
<ItemTemplate>
<table border = "1">
<tr>
<td id = "CheckBoxCell" runat = "server"><asp:CheckBox ID="CheckBox1" runat="server" /></td>
<td style = "width:150px"><b>Coupon: </b><asp:Label ID="lblCoupon" runat="server" Text='<%# Eval("Coupon") %>'></asp:Label></td>
<td style = "width:100px"><b>Code: </b><asp:Label ID="lblCode" runat="server" Text='<%# Eval("Code") %>'></asp:Label></td>
</tr>
</table>
</ItemTemplate>
