我有未来的JTable
private void initComponents() {
jScrollPane1 = new javax.swing.JScrollPane();
jTable1 = new javax.swing.JTable();
jButton1 = new javax.swing.JButton();
jButton2 = new javax.swing.JButton();
setDefaultCloseOperation(javax.swing.WindowConstants.EXIT_ON_CLOSE);
getContentPane().setLayout(null);
jTable1.setModel(new javax.swing.table.DefaultTableModel(
new Object [][] {
{"Hat", "New York", "1000"},
{"T-Shirt", "New York", "3500"},
{"Sweater", "Washington", "2800"},
{"Bag", "California", "7000"},
},
new String [] {
"Name", "Warehouse", "Quantity"
}
));
jScrollPane1.setViewportView(jTable1);
getContentPane().add(jScrollPane1);
jScrollPane1.setBounds(19, 11, 375, 170);
jButton1.setText("Copy");
getContentPane().add(jButton1);
jButton1.setBounds(113, 195, 63, 23);
jButton2.setText("Exit");
getContentPane().add(jButton2);
jButton2.setBounds(225, 195, 53, 23);
pack();
}
我想按钮复制模式到剪贴板的信息,但它不工作,我已经尝试使用
String myString = "This text will be copied into clipboard when running this code!";
StringSelection stringSelection = new StringSelection (myString);
Clipboard clpbrd = Toolkit.getDefaultToolkit ().getSystemClipboard ();
clpbrd.setContents (stringSelection, null);
这个概念比较简单,实施更复杂一点。
关键是要找到各种应用将承认并允许你转换你的数据的MIME类型。
我不包括CSV翻译,它不会花费太多来获取从示例代码的工作,另外,我还没有包括在任何表格单元格值“格式化”,我相信你能明白这出来为好。

JTable中的默认复制功能将复制选定的数据行到剪贴板。
见行动地图行动的一个方法,让您可以访问此动作。 使用提供的类的代码如下:
Action copyAction = new ActionMapAction("Copy Table", table, "copy");
JButton copyButton = new JButton(copyAction);
