的Javascript：

function sortTable(table, col, reverse) { 
    var tb = table.tBodies[0], // use `<tbody>` to ignore `<thead>` and `<tfoot>` rows 
     tr = Array.prototype.slice.call(tb.rows, 0), // put rows into array 
     i; 
    reverse = -((+reverse) || -1); 
    tr = tr.sort(function (a, b) { // sort rows 
     return reverse // `-1 *` if want opposite order 
      * (a.cells[col].textContent.trim() // using `.textContent.trim()` for test 
       .localeCompare(b.cells[col].textContent.trim()) 
       ); 
    }); 
    for(i = 0; i < tr.length; ++i) tb.appendChild(tr[i]); // append each row in order 
} 

function makeSortable(table) { 
    var th = table.tHead, i; 
    th && (th = th.rows[0]) && (th = th.cells); 
    if (th) i = th.length; 
    else return; // if no `<thead>` then do nothing 
    while (--i >= 0) (function (i) { 
     var dir = 1; 
     th[i].addEventListener('click', function() {sortTable(table, i, (dir = 1 - dir))}); 
    }(i)); 
} 

function makeAllSortable(parent) { 
    parent = parent || document.body; 
    var t = parent.getElementsByTagName('table'), i = t.length; 
    while (--i >= 0) makeSortable(t[i]); 
} 

window.onload = function() {makeAllSortable();}; 

CSS：

table {width: 100%;font: 12px arial;} 
th, td {min-width: 40px;text-align: center;} 
th {font-weight: bold;cursor:pointer;}

你的价值观排序为文本。你应该将数值转换为int。使用parseFloat将字符串值转换为数字并对它们进行排序。

tr = tr.sort(function (a, b) { // sort rows 
    str_a = a.cells[col].textContent.trim() 
    str_b = b.cells[col].textContent.trim() 
    val_a = parseFloat(str_a) 
    val_b = parseFloat(str_b) 

    if(!isNaN(val_a) && !isNaN(val_b)){ 
     var compar; 
     if(val_a < val_b){ 
      compar = -1; 
     }else if(val_a > val_b){ 
      compar = 1; 
     }else{ 
      compar = 0; 
     } 
     return reverse*compar; 
    } 
    ... 
    ... 
...
