ページの読み込み時に JavaScript を使用してスクロール可能なテーブルを作成しました テーブルの可視性はデフォルトで非表示になっています。IE でページを最小化/最大化すると、ブラウザによって非表示のテーブルが表示されます。誰でもこの問題を解決するのを手伝ってくれますか?

スクロール可能なテーブルを作成する JavaScript は次のとおりです。

      /* 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;
            }
          }
        }
function ScrollableTable (tableEl, maxRows, tableWidth) {
 var tableHeight = 25 + maxRows * 25;

 var numRows = 0;
    this.initIEengine = function () {

        if (this.tableEl.parentElement.clientHeight - this.tableEl.offsetHeight < 0) {
            this.tableEl.style.width = this.newWidth - this.scrollWidth +'px';
        }

        if (this.thead) {

            var trs = this.thead.getElementsByTagName('tr');                
            for (x=0; x<trs.length; x++) {
                trs[x].style.position ='relative';
                trs[x].style.setExpression("top",  "this.parentElement.parentElement.parentElement.scrollTop + 'px'");
            }           
        }


        if (this.tfoot) {
            var trs = this.tfoot.getElementsByTagName('tr');             
            for (x=0; x<trs.length; x++) {
                trs[x].style.position ='relative';              
                trs[x].style.setExpression("bottom",  "(this.parentElement.parentElement.offsetHeight - this.parentElement.parentElement.parentElement.clientHeight - this.parentElement.parentElement.parentElement.scrollTop) + 'px'");
            }
        }       

        eval("window.attachEvent('onresize', function () { document.getElementById('" + this.tableEl.id + "').style.visibility = 'hidden'; document.getElementById('" + this.tableEl.id + "').style.visibility = 'visible'; } )");
    };

        var tds; 

        if (bodyHeight >= (this.newHeight - (headHeight + footHeight))) {       
             for (x=0; x<trs.length; x++) {
                tds = trs[x].getElementsByTagName('td');
                tds[tds.length-1].style.paddingRight += this.scrollWidth + 'px';

ページの高さが変わったときにテーブルを強制的にスクロールすることもできます。CSS で、この属性をテーブルのコンテナーに適用できます。overflow-y:scroll;
