Delete a row from a table by id

How about:

function deleteRow(rowid)  
{   
    var row = document.getElementById(rowid);
    row.parentNode.removeChild(row);
}

And, if that fails, this should really work:

function deleteRow(rowid)  
{   
    var row = document.getElementById(rowid);
    var table = row.parentNode;
    while ( table && table.tagName != 'TABLE' )
        table = table.parentNode;
    if ( !table )
        return;
    table.deleteRow(row.rowIndex);
}
