IE8显示可滚动表的隐藏问题

我使用javascript在页面加载时创建了一个可搜索的表默认情况下，表的可见性是隐藏的。当我在IE中最小化/最大化页面时，浏览器会使隐藏的表可见。有人能帮我解决这个问题吗。

创建可滚动表的javascript如下

      /* Scrollable table */
       function setScrollableTableHeight(name,maxrows)
       {
        var count;
            var arrObj = document.getElementsByName(name);              
            for(count=0;count<arrObj.length;count++)
            {
                ScrollableTable(arrObj[0], maxrows);
            }              
       }
        // set Body width to screen width
        function setBodyWidth()
        {
          objBody = document.getElementsByTagName('body');
          objBody[0].style.width = screen.width - 40;
          var objDivs = document.getElementsByTagName('div');
          for(var i=0;i<objDivs.length;i++)
          {
            if(objDivs[i].className == "OuterPanel")
            {
                if(screen.width < 980)
                    objDivs[0].style.width = 980 - 42;
                else
                    objDivs[0].style.width = screen.width - 42;
                break;
            }
          }
        }
