I have a dynamic table which has a number of rows like this:

<table id="wpt_tb">
<tbody>
<tr id="tb28791794">
<td>blah</td>
<td>blah</td>
</tr>
<tr id="tb28792890">
<td>blah</td>
<td>blah</td>
</tr>
</table>

I want to be able to remove 1 of the rows from the table
 I tried this code but it does not work:

var tb = document.getElementById("wpt_tb");
var rw = document.getElementById("tb28791794");
tb.removeChild(rw);

In Firefox it generates this error:
uncaught exception: [Exception... "Component returned failure code: 0x80004003 (NS_ERROR_INVALID_POINTER) [nsIDOMHTMLTableElement.removeChild]"  nsresult: "0x80004003"

In Internet Explorer it gives error "Invalid argument"

Please help! Thanks.
