javascript table排序 这个更简单了，不用改变现在的表格结构

JavaScript实现可自定义排序的表格 -

BODY {
FONT-SIZE: 0.8em; FONT-FAMILY: Trebuchet MS, Lucida Sans Unicode, Arial, sans-serif
}
P {
FONT-WEIGHT: bold; MARGIN-BOTTOM: 0px
}
.tableWidget_headerCell {
BORDER-RIGHT: #aca899 1px solid; BORDER-LEFT: #fff 1px solid; CURSOR: pointer; BORDER-BOTTOM: #c5c2b2 3px solid; BACKGROUND-COLOR: #ece9d8
}
.tableWigdet_headerCellOver {
BORDER-RIGHT: #aca899 1px solid; BORDER-LEFT: #fff 1px solid; CURSOR: pointer; BORDER-BOTTOM: #c5c2b2 3px solid; BACKGROUND-COLOR: #ece9d8
}
.tableWigdet_headerCellDown {
BORDER-RIGHT: #aca899 1px solid; BORDER-LEFT: #fff 1px solid; CURSOR: pointer; BORDER-BOTTOM: #c5c2b2 3px solid; BACKGROUND-COLOR: #ece9d8
}
.tableWidget_headerCell {
