tr+border+IE

Is it possible that IE can not use border for <tr>?
In my example:

Mam takie co¶:
[css]
table.dft{
width:100%;
border-collapse:collapse;
}
table.dft tbody tr{
border-bottom:1px solid #e5e5e5;
}

[html]
<table class="dft">
....
<tbody>
<tr>
<td>...</td><td>...</td><td>...</td>
</tr>
....
</tbody>

IE do not show a 1px line with #e5e5e5 color, but Firefox and Opera
works fine.

Any ideas?
