这是我到目前为止,但它甚至没有提示用户,它显示一条细黑线(我认为是边界)

我尝试将它包含在头部和身体中,我也尝试在脚本和脚本之外声明表标记。

您的代码中存在一些错误,例如:
<table style = "width:100%" cellspacing="5" border="2">
你不能将html代码放在head中,你需要在body上写这个。
var input[i]; //variable that holds the input values
您无法定义包含密钥的变量。正确的方法是:
var input = [];
其他
switch(num1):
// ... code
正确的方法是:
switch(num1) {
// ... code
}
您可以使用html validator检查html错误,如果您使用的是Firefox或Chrome等现代浏览器,则可以按f12访问javascript错误。

您的代码有几个javascript错误。试试这个开头:
<html>
<head>
<meta charset = "utf-8">
<title>Dynamically creating a table</title>
<table style = "width:100%" cellspacing="5" border="2">
<script type = "text/javascript">
var running = true; //boolean to determine if we should continue running
while (running) {
var input = window.prompt("Please enter your two numbers seperated by a comma.");
var split = input.split(',');
var num1= split[0];
var num2= input[1];
switch(num1) {
case '1':
document.writeln("<tr>");
document.writeln("<td>text</td>");
document.writeln("<td>text</td>");
document.writeln("</tr>");
case '2':
document.writeln("<tr>");
document.writeln("<td>text1</td>");
document.writeln("<td>text2</td>");
document.writeln("<td>text3</td>");
document.writeln("</tr>");
case '99':
running = false;
}
}
</script>
</table>
</head>
<body>
