1、index.html文件:

<html>

 font:  Message-Box;
}
code {
 font-size: 1em;
}
</style>
</head>
<body>
<table id="MyHeadTab" cellspacing="0" onclick="sortColumn(event)">
 <thead>
 <tr>
  <td>String</td>
  <td title="CaseInsensitiveString">String</td>
  <td>Number</td>
  <td>Date</td>
  <td>No Sort</td>

 <tr>
  <td>blueberry</td>
  <td>Pear</td>
  <td>4</td>
  <td>2001-04-18</td>
  <td>Item 5</td>
 </tr>
  </tbody>
</table>
</body>
</html>

2、tablesort.js文件:

var dom = (document.getElementsByTagName) ? true : false;
var ie5 = (document.getElementsByTagName && document.all) ? true : false;
var arrowUp, arrowDown;
if (ie5 || dom)
 initSortTable();
function initSortTable() {
 arrowUp = document.createElement("SPAN");
 var tn = document.createTextNode("5");
 arrowUp.appendChild(tn);
 arrowUp.className = "arrow";
 arrowDown = document.createElement("SPAN");
 var tn = document.createTextNode("6");
 arrowDown.appendChild(tn);
 arrowDown.className = "arrow";
}
function sortTable(tableNode, nCol, bDesc, sType) {
 var tBody = tableNode.tBodies[0];
 var trs = tBody.rows;
 var trl= trs.length;
 var a = new Array();
 for (var i = 0; i < trl; i++) {
 a[i] = trs[i];
 }
 var start = new Date;
 window.status = "Sorting data...";
 a.sort(compareByColumn(nCol,bDesc,sType));
 window.status = "Sorting data done";
 for (var i = 0; i < trl; i++) {
 tBody.appendChild(a[i]);
 window.status = "Updating row " + (i + 1) + " of " + trl +
   " (Time spent: " + (new Date - start) + "ms)";
 }
 // check for onsort
 if (typeof tableNode.onsort == "string")
 tableNode.onsort = new Function("", tableNode.onsort);
 if (typeof tableNode.onsort == "function")
 tableNode.onsort();
}
function CaseInsensitiveString(s) {
 return String(s).toUpperCase();
}
function parseDate(s) {
 return Date.parse(s.replace(/\/-/g, '/'));
}
/* alternative to number function
 * This one is slower but can handle non numerical characters in
 * the string allow strings like the follow (as well as a lot more)
 * to be used:
 *  "1,000,000"
 *  "1 000 000"
 *  "100cm"
 */
function toNumber(s) {
  return Number(s.replace(/[^0-9/.]/g, ""));
}
function compareByColumn(nCol, bDescending, sType) {
 var c = nCol;
 var d = bDescending;
 var fTypeCast = String;
 if (sType == "Number")
 fTypeCast = Number;
 else if (sType == "Date")
 fTypeCast = parseDate;
 else if (sType == "CaseInsensitiveString")
 fTypeCast = CaseInsensitiveString;
 return function (n1, n2) {
 if (fTypeCast(getInnerText(n1.cells[c])) < fTypeCast(getInnerText(n2.cells[c])))
  return d ? -1 : +1;
 if (fTypeCast(getInnerText(n1.cells[c])) > fTypeCast(getInnerText(n2.cells[c])))
  return d ? +1 : -1;
 return 0;
 };
}
function sortColumnWithHold(e) {
 // find table element
 var el = ie5 ? e.srcElement : e.target;
 var table = getParent(el, "TABLE");
 // backup old cursor and onclick
 var oldCursor = table.style.cursor;
 var oldClick = table.onclick;
 // change cursor and onclick 
 table.style.cursor = "wait";
 table.onclick = null;
 // the event object is destroyed after this thread but we only need
 // the srcElement and/or the target
 var fakeEvent = {srcElement : e.srcElement, target : e.target};
 // call sortColumn in a new thread to allow the ui thread to be updated
 // with the cursor/onclick
 window.setTimeout(function () {
 sortColumn(fakeEvent);
 // once done resore cursor and onclick
 table.style.cursor = oldCursor;
 table.onclick = oldClick;
 }, 100);
}
function sortColumn(e) {
 var tmp = e.target ? e.target : e.srcElement;
 var tHeadParent = getParent(tmp, "THEAD");
 var el = getParent(tmp, "TD");
 if (tHeadParent == null)
 return;
 if (el != null) {
 var p = el.parentNode;
 var i;
 // typecast to Boolean
 el._descending = !Boolean(el._descending);
 if (tHeadParent.arrow != null) {
  if (tHeadParent.arrow.parentNode != el) {
  tHeadParent.arrow.parentNode._descending = null; //reset sort order 
  }
  tHeadParent.arrow.parentNode.removeChild(tHeadParent.arrow);
 }
 if (el._descending)
  tHeadParent.arrow = arrowUp.cloneNode(true);
 else
  tHeadParent.arrow = arrowDown.cloneNode(true);
 el.appendChild(tHeadParent.arrow);
 // get the index of the td
 var cells = p.cells;
 var l = cells.length;
 for (i = 0; i < l; i++) {
  if (cells[i] == el) break;
 }
 var table = getParent(el, "TABLE");
 // can't fail
 sortTable(table,i,el._descending, el.getAttribute("type"));
 }
}
function getInnerText(el) {
 if (ie5) return el.innerText; //Not needed but it is faster
 var str = "";
 var cs = el.childNodes;
 var l = cs.length;
 for (var i = 0; i < l; i++) {
 switch (cs[i].nodeType) {
  case 1: //ELEMENT_NODE
  str += getInnerText(cs[i]);
  break;
  case 3: //TEXT_NODE
  str += cs[i].nodeValue;
  break;
 }
 }
 return str;
}
function getParent(el, pTagName) {
 if (el == null) return null;
 else if (el.nodeType == 1 && el.tagName.toLowerCase() == pTagName.toLowerCase()) // Gecko bug, supposed to be uppercase
 return el;
 else
 return getParent(el.parentNode, pTagName);
}

3、tablesort.css文件:

tr  {background: window;}
td  {color: windowtext; font: menu; padding: 1px; padding-left: 5px; padding-right: 5px;
  border-right: 1px solid buttonshadow;
  border-bottom: 1px solid buttonshadow;
}
table {border-top: 1px solid buttonshadow;
  border-left: 1px solid buttonshadow;
  border-right: 1px solid buttonhighlight;
  border-bottom: 1px solid buttonhighlight;
   }
thead td {background: buttonface; font: menu; border: 1px outset white;
  padding-top: 0; padding: bottom: 0;
  border-top: 1px solid buttonhighlight;
  border-left: 1px solid buttonhighlight;
  border-right: 1px solid buttonshadow;
  border-bottom: 1px solid buttonshadow;
  height: 16px;
}
thead .arrow{font-family: webdings; color: black; padding: 0; font-size: 10px;
  height: 11px; width: 10px; overflow: hidden;
  margin-bottom: 5; margin-top: -3; padding: 0; padding-top: 0; padding-bottom: 2;}
  /*nice vertical positioning :-) */
