I have some code to sort the body of a table that is all numbers. It works on firefox, but on chrome it does not update the table. On chrome, the sort function does not seem to change the order of the tr elements in the array.

function sortTable(col, dir = 1) {

    var tb = document.getElementById("vote_table").tBodies[0];
    tr = Array.prototype.slice.call(tb.rows, 0);

    tr = tr.sort(
            function (a, b) 
            { 
                return dir*parseInt(a.cells[col].textContent) < dir*parseInt(b.cells[col].textContent);               
            }
       );
    
    alert(tr[0].cells[col].textContent);

    for(var i = 0; i < tr.length; ++i) 
    { 
        tb.appendChild(tr[i]);  
    } // append each row in order
}
