• 设置表列标题
  
  • Set the table column headers
    
    
    1. 在设计视图中高亮显示表格，然后转到右侧的属性窗格。应该是一个标题为属性的标签。确保突出显示该表而不是其周围的滚动窗格，否则下一步将无法工作
    
    
    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

    1. Right-click on the button and select Events -> Action -> actionPerformed

    2. You should see code like the following auto-generated

    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.
    }
    

  
  

  所以对于每一套通过几个文本字段，组合框和复选框等数据，您可以在每次按下按钮时收集该数据，并将其作为一行添加到模型中。

  So for every set of data like from a couple text fields, a combo box, and a check box, you can gather that data each time the button is pressed and add it as a row to the model.
