将带有网格线的jTable行复制到excel / word文档中

是否可以复制jTable行并将其粘贴到word文档或带有格式化网格的新电子邮件中（彩色水平和垂直网格线）..如果是，如何？

当我从jTable复制一行并将其粘贴到word文档中时，Word会将其识别为表格行，但我必须通过添加网格线并将其着色来设置它的样式

Answer 1

这是将一行数据复制到基于HTML的表中的非常简单的示例。 我能够复制任何行并粘贴到word作为基于HTML的表而没有（到很多）问题

"); sb.append(table.getValueAt(row, col).toString()); sb.append("
"); Clipboard clipboard = Toolkit.getDefaultToolkit().getSystemClipboard(); clipboard.setContents(new HtmlSelection(sb.toString()), null); } }); JFrame frame = new JFrame("Testing"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.add(new JScrollPane(table)); frame.pack(); frame.setLocationRelativeTo(null); frame.setVisible(true); } }); } private static class HtmlSelection implements Transferable { private static ArrayList htmlFlavors = new ArrayList(); static { try { htmlFlavors.add(new DataFlavor("text/html;class=java.lang.String")); htmlFlavors.add(new DataFlavor("text/html;class=java.io.Reader")); htmlFlavors.add(new DataFlavor("text/html;charset=unicode;class=java.io.InputStream")); } catch (ClassNotFoundException ex) { ex.printStackTrace(); } } private String html; public HtmlSelection(String html) { this.html = html; } public DataFlavor[] getTransferDataFlavors() { return (DataFlavor[]) htmlFlavors.toArray(new DataFlavor[htmlFlavors.size()]); } public boolean isDataFlavorSupported(DataFlavor flavor) { return htmlFlavors.contains(flavor); } public Object getTransferData(DataFlavor flavor) throws UnsupportedFlavorException { if (String.class.equals(flavor.getRepresentationClass())) { return html; } else if (Reader.class.equals(flavor.getRepresentationClass())) { return new StringReader(html); } else if (InputStream.class.equals(flavor.getRepresentationClass())) { return new StringBufferInputStream(html); } throw new UnsupportedFlavorException(flavor); } } } 

这是非常有限的，因为这将简单地使用每个单元格的toString方法来获取单元格的值，这意味着单元格值不会根据值类型或应用程序要求“格式化”。 您将不得不设计一个解决方案，将单元格值格式化为String
