推荐答案

设置表列标题

  2. 单击右侧的按钮财产模型。将出现一个对话框。
  3. 将行设置为0，设置所需的列数及其名称。
  1. Highglight the table in the design view then go to properties pane on the very right. Should be a tab that says "Properties". Make sure to highlight the table and not the scroll pane surrounding it, or the next step wont work
  2. Click on the button to the right of the property model. A dialog should appear.
  3. Set rows to 0, set the number of columns you want, and their names.
- 在框架中添加一个按钮。当用户准备提交行时，将单击此按钮
- Add a button to the frame somwhere,. This button will be clicked when the user is ready to submit a row
  1. 右键单击按钮并选择活动 - >行动 - > actionPerformed
  2. 你应该看到如下自动生成的代码

private void jButton1ActionPerformed(java.awt.event.ActionEvent) {}
```
- jTable1 将有一个 DefaultTableModel 。您可以使用数据向模型添加行
- The jTable1 will have a DefaultTableModel. You can add rows to the model with your data
```
private void jButton1ActionPerformed(java.awt.event.ActionEvent) {
    String data1 = something1.getSomething();
    String data2 = something2.getSomething();
    String data3 = something3.getSomething();
    String data4 = something4.getSomething();

    Object[] row = { data1, data2, data3, data4 };

    DefaultTableModel model = (DefaultTableModel) jTable1.getModel();

    model.addRow(row);

    // clear the entries.
}
