[解决办法]
这是楼主跟你原来差不多的
修改后
<html>
<head>
<title>test page</title>
<script type='text/javascript'>
function createTable() {
var t = document.createElement('table');
var row = document.getElementsByName("rownum")[0].value;
var col = document.getElementsByName("colnum")[0].value;
for (var i = 0; i < row; i++) {
var r = t.insertRow();
for (var j = 0; j < col; j++) {
var c = r.insertCell();
c.innerHTML = i + ',' + j;
}
}
document.getElementById('table1').appendChild(t);
t.setAttribute('border', '1');
}

</script>

<body>
行：<input type="text" name="rownum" /><br />
列：<input type="text" name="colnum" /><br />
<input type="button" value="创建表格" onclick="createTable()" /><br />
