目前我正在使用此代码在 Javascript 中创建动态表，但我不知道如何将数据从我的数组添加到此单元格？

我正在使用以下代码：

border-collapse:collapse;
width:200px;
}
.mytable td{
background:#cccccc;
border:1px solid #000000;
}
</style>

<script type="text/javascript">
onload=function(){
var nrCols=1;
var maxRows=10;
var nrRows=maxRows+1;
var news=new Array();
while(nrRows>maxRows){
news[0]="one";
nrRows=Number(prompt('How many rows? Maximum '+maxRows+' allowed.',''));
}
var root=document.getElementById('mydiv');
var tab=document.createElement('table');
tab.className="mytable";
var tbo=document.createElement('tbody');
var row, cell;
for(var i=0;i<nrRows;i++){
    row=document.createElement('tr');
    for(var j=0;j<nrCols;j++){
        cell=document.createElement('td');
        cell.appendChild(document.createTextNode(news[0]));
        row.appendChild(cell);
    }
    tbo.appendChild(row);
}
tab.appendChild(tbo);
root.appendChild(tab);
}
</script>
</head>
<body>
<div id="mydiv" style="width:300 px;height:100 px overflow:scroll"></div>
</body>
</html>
