当单元格中没有数据时表格边框

Question

I have a table that has a couple of cells that do not contain data:

<table id="table_id2" CellPadding="0" CellSpacing="0" border="1">
 <tr style="background-color:#D1DEB6"><td>Test 1</td><td class="y_n">Y</td></tr>
 <tr style="background-color:#C7D6A7"><td>Test 2</td><td class="y_n">N</td></tr>
 <tr style="background-color:#D1DEB6"><td></td><td class="y_n">Y</td></tr>
 <tr style="background-color:#C7D6A7"><td></td><td class="y_n">Y</td></tr>
</table>

I you look carefully you'll notice the borders are inconsistant. The borders appear but not for the cells without any data in them. Does anyone know a solution to this? I know you can put a &nbsp in to get the borders but this isn't an option for me the reason being that some cell have labels in them like:

<asp:Label ID="Label2" runat="server" Text='<%# Eval("Name") %>' />

It's causing problems when say the Name is null then I'm missing the borders for the empty cell.

If you don't want to mess with CSS you could wrap your Eval call in a formatting function from your code behind page to check for an empty string and then return a   :

<asp:Label ID="Label2" runat="server" Text='<%# InsertNBSP(Eval("Name")) %>' />

On code behind:

public string InsertNBSP(string str)
{
    if(str == "")
       return " "
    else
       return str;
}
