CSS border issue on colspan TD

Question

Hi guys, I have a CSS problem regarding borders, the problem is adding borders around td with colspan. The table has the properties:

<table cellspacing=0 cellpadding=0 border=0>

CSS style:

.tdclass{
    background-color:#FDBCC1;
}

.tdclass td{
    border-top: 3px solid white;
}

How it works:

<tr class = "tdclass">
<td> ...
<td colspan="2"> ...
<td> ...
</tr>

What this CSS does is highlight a row of lines and add a white line that acts as the spacing between fake rows. Adding borders to an element <tr>does not work, only works on <td>.

, "colspan" . , , , , ".tdclass". "colspan" <td>. , , :
