【问题描述】：
我正在尝试为某些特定项目实现仅查看 HTML 窗格。我正在使用JTextPane 使用内容类型为"text/html" 呈现HTML。我的输入 HTML 中有表格，所以为了给这些表格提供边框，我想使用 css 样式，但不幸的是它没有成功。
如果我将边框属性作为表格本身的一部分，那么它可以工作，但不能 使用 css 样式。
这是我为重新创建问题而创建的示例代码。 content1 不会为我的表格创建边框，但 content2 会创建它。我想使用 content1 方法，因为我有很多带有表格的 html 文件。感谢您的宝贵时间，我们将不胜感激。

【问题讨论】：
-
在样式中添加
tr以及为 content1 添加table,tr, th, td { border: 1px solid black }
