我正在w3school上创建程序，它根本不提供任何调试工具，我基本上在那里完成了我的项目，但后来发现我有80多个错误需要修复，这些错误已得到超级通用答案，因此我似乎无法弄清楚到底是什么问题。我是HTML的超级新手，与Java不同，Eclipse至少会告诉您错误的确切位置，并为您提供更好的信息，我不知道错误的含义。我也在使用w3school文件上传方法来调试程序。而且我的节目基本上只是一个电视时间表，其中包含了日期，时间，每个节目都有细分
我尝试谷歌搜索一些答案，但没有帮助

我只会遇到这类错误， -文档类型此处不允许元素“表”
答案 0 :(得分：1)
您缺少head和body标签。您需要有效的html。您的表必须包含在body标记中。
<html>
<head>
</head>
<body>
<table>
<!--All your table stuff-->
</table>
</body>
</html>
还要确保您拥有所有结束标签。我注意到缺少一些</th>标签。
更新：您正在使用的XHTML中xmlns属性是必需的。您需要将上述属性添加到您的html标记中：
<html xmlns="http://www.w3.org/1999/xhtml">
<!--head,body,etc-->
</html>
可以在w3Schools上找到
您面临的大多数问题的根源是缺少标签。使用任何标记或编程语言编写时，请确保您与打开分组的同时具有相同数量的打开标记/括号/分组。否则，此问题可能很难在代码中发现，并且可能导致一些最糟糕的结果。
