table 自由拉伸

外層div的樣式:
div{
      position:absolute;
      overflow:auto;     
      scrollbar-face-color:9999ff;     
      height:expression((document.body.clientHeight-this.offsetTop-15>this.children[0].offsetHeight)?(this.children[0].offsetHeight+15):(document.body.clientHeight-this.offsetTop-15));     
      width:expression(document.body.clientWidth-15);
}
內層table的第一行的樣式:
fixedheadtr{
   position:absolute;     
   top:expression(this.offsetParent.scrollTop); 
   background-color:navy;
   cursor:hand;
   height:32px;
}
table的style="behavior:url(grid.htc)"
