I would use this CSS rule:

#HMP_options table tr:nth-child(-2n + 4) {
    display: none;
}

Since this is IE9+ you might want to make jQuery help it.

In this example I assumed that you want only hide 2nd and 4th row. If you want to hide 6th, 8th and so on as well you should use :nth-child(2n) rule.

try this

.HMP_options > table td:nth-child(2),
.HMP_options > table td:nth-child(4) { display:none;}

Using css:

.HMP_options tr:nth-child(2), .HMP_options tr:nth-child(4){display: none;}

Using jQuery:

$('.HMP_options tr:nth-child(2), .HMP_options tr:nth-child(4)').css('display','none');

Use eq in jquery . Select the element at index n within the matched set. Zero-based index of the element to match.

 $("tr:eq(1),tr:eq(4)").hide();
