使用CSS的HTML表格格式在JTextPane中不起作用
[英]HTML Table formatting using css not working in JTextPane
問題描述
我正在嘗試為某些特定項目實現僅查看HTML窗格。 我正在使用JTextPane來使用內容類型為"text/html"來呈現HTML。 我在輸入HTML中有表格，因此為了給這些表格加上邊框，我想到了使用CSS樣式，但不幸的是，它沒有奏效。
如果我將border屬性作為表本身的一部分，則它可以工作，但不能用於CSS樣式。
這是我為重現問題而創建的示例代碼。 content1不會為我的表創建邊框，但是content2會創建它。 我想使用content1方法，因為我有很多帶有表的html文件。 感謝您的寶貴時間，我們將不勝感激。

我從樣式中刪除了注釋符號，並添加了字體大小的單位。
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTextPane;
public class TestTextPane {
private static int X = 200;
private static int Y = 200;
private static int W = 600;
private static int H = 400;
public static final String content1 = "<html>\r\n" +
" <head>\r\n" +
" <style type=\"text/css\">\r\n" +
" table, th, td { border: 2px solid #FF0000; }\r\n" +
// be sure to add a unit to the font size, otherwise it is invalid
" body, p { font-family: Courier; font-size: 14px; }\r\n" +
" </style>\r\n" +
" \r\n" +
" </head>\r\n" +
" <body>\r\n" +
" <div align=\"left\">\r\n" +
" <b>Q: What is the difference between GET and POST method? </b>\r\n" +
" </div>\r\n" +
" <p>\r\n" +
" A:\r\n" +
" </p>\r\n" +
" <table>\r\n" +

JTextPane pane = new JTextPane();
pane.setContentType("text/html");
pane.setEditable(false);
JScrollPane scrollPane = new JScrollPane(pane);
scrollPane.setBounds(X,Y,W,H);
frame.getContentPane().add(scrollPane);

這就是我為content1嘗試的方法，並且工作正常。
我加了這條線
body table { border: 1px solid red }
樣例代碼：
public static final String content1 = "<html>\r\n"
+ " <head>\r\n"
+ " <style type=\"text/css\">\r\n"
+ " <!--\r\n"
+ " table, th, td { border: 1px solid black }\r\n"
+ " body table { border: 1px solid red }\r\n"
+ " body, p { font-family: Courier; font-size: 14; }\r\n"
+ " -->\r\n"
+ " </style>\r\n"

我嘗試了上述所有解決方案，但不幸的是，這些解決方案均不適合我。 我正在尋找解決方案，因此進入了這篇文章
我試過了table, th, td { border-width: 1px solid black }瞧這對我有用。 我不知道為什么普通邊境財產對我不起作用，但對其他人卻起作用。
非常感謝您提供的所有幫助。
