Vise og skjule en TD eller TR

<script language="javascript">
function vismenu(cID)
{
    if (document.getElementById(cid).style.display == "none")
        {
            document.getElementById(cID).style.display = "block";
        }
    else
        {
            document.getElementById(cID).style.display = "none";
        }
}
</script>
<table border="0" width="200">
<tr id="minTr1">
<td>tekst</td>
</tr>
<tr id="minTr2">
<td>min anden tekst">
</tr>
</table>

sorry.. var vist lidt mere end hurtig :(

Det her virker:

<script language="javascript">
function visSkjul(cID)
{
    var tr = document.getElementById(cID);
    if (tr.style.display == "none")
        {
            tr.style.display = "block";
        }
    else
        {
            tr.style.display = "none";
        }
}
</script>
<table border="0" width="200">
<tr name="minTr1" id="minTr1">
<td>tekst</td>
</tr>
<tr name="minTr2" id="minTr2" style="display: none;">
<td>min anden tekst</td>
</tr>
</table>
<input type="button" value="clicky" onclick="visSkjul('minTr2');">
