I can get the inline style for ay element with style selector, but here I am not able to get the style as its inside tag.我可以使用样式选择器获取 ay 元素的内联样式，但在这里我无法将样式作为其内部标记。

Is there any way that I can get the style for each TD, TR and also the special class style?有什么方法可以让我获得每个 TD、TR 以及特殊的 class 风格的风格？ Thanks in advance提前致谢

Internal css described as style attribute , not as element like inline css.内部 css 描述为样式属性，而不是像内联 css 这样的元素。 So you have to get internal css with attr() method.因此，您必须使用 attr() 方法获取内部 css 。 For example:例如：

Document htmlFile = Jsoup.parse(html);
Element firstTableElem = htmlFile.select("table").first();
String tableStyleValue = firstTableElem.attr("style"); //gives you internal css
