一个Javascript 的类库，用于table内容排序。使用很方便，不用每次都去调用数据库了。
特别适合多表查询的排序。加上

的style.display 切换，也可以实现分页。
效果演示
用法:
1.添加JS
<script></script>
2.添加TABLE,注意的是：一定要有ID,class为"sortable"

OK,可以了，简单的吧
如果觉得太单调，自己加点CSS吧，官方给出了改HEAD的CSS

/* Sortable tables */
table.sortable a.sortheader {
    background-color:#eee;
    color:#666666;
    font-weight: bold;
    text-decoration: none;
    display: block;
}
table.sortable span.sortarrow {
    color:black;
    text-decoration: none;
}

复制代码代码如下:

addEvent(window, "load", sortables_init);

var SORT_COLUMN_INDEX;

function sortables_init() {
    // Find all tables with class sortable and make them sortable
    if (!document.getElementsByTagName) return;
    tbls = document.getElementsByTagName("table");
    for (ti=0;ti        thisTbl = tbls[ti];
        if (((' '+thisTbl.className+' ').indexOf("sortable") != -1) && (thisTbl.id)) {
            //initTable(thisTbl.id);
            ts_makeSortable(thisTbl);
        }
    }
}

function ts_makeSortable(table) {
    if (table.rows && table.rows.length > 0) {
        var firstRow = table.rows[0];
    }
    if (!firstRow) return;

    // We have a first row: assume it's the header, and make its contents clickable links
    for (var i=0;i        var cell = firstRow.cells[i];
        var txt = ts_getInnerText(cell);
        cell.innerHTML = '        'onclick="ts_resortTable(this, '+i+');return false;">' +
        txt+'   ';
    }
}

function ts_getInnerText(el) {
    if (typeof el == "string") return el;
    if (typeof el == "undefined") { return el };
    if (el.innerText) return el.innerText;    //Not needed but it is faster
    var str = "";

    var cs = el.childNodes;
    var l = cs.length;
    for (var i = 0; i         switch (cs[i].nodeType) {
            case 1: //ELEMENT_NODE
                str += ts_getInnerText(cs[i]);
                break;
            case 3:    //TEXT_NODE
                str += cs[i].nodeValue;
                break;
        }
    }
    return str;
}

    // get the span
    var span;
    for (var ci=0;ci        if (lnk.childNodes[ci].tagName && lnk.childNodes[ci].tagName.toLowerCase() == 'span') span = lnk.childNodes[ci];
    }

    // Delete any other arrows there may be showing
