我有一个 ArrayString，其中包含一些我想在 GUI 上打印的数据，我开始使用 JPanel 等，最后使用 Eclipse 上的 windowbuilder 来帮助我修改视觉方面，我认为我的代码很糟糕(或者至少看起来像这样)我发现了一些与我的问题类似的线索，但我并没有真正理解这个想法:
我可以不使用 Jtable 来代替看起来像一堆垃圾的东西吗？我只是无法理解 JTable，我希望它看起来就像我的代码输出，但我不明白该表如何读取数组字符串以及如何像我的表一样“输出它”，我不知道如何实现组合框...任何帮助都会很有用，谢谢!
编辑:我的第一个想法是每个“Jtextfield”都会“导入”每个数据行，但我认为这是非常低效的，并且当我可以让我的生活更简单时可能容易出现编码错误？

最佳答案
创建表和模型，然后创建列标题:
DefaultTableModel dftModel = new DefaultTableModel();
JTable mytable = new JTable(dftModel);
myTable.setColumnIdentifiers(new String [] {"Tipo","Column 1","Column 2","Column 3"});
根据需要从数组列表中添加行:
myTable.addRow(new String[] {"",yourArrayList.get(1),"blah","blah"});
像这样添加您的 Tipo 组合框:
String [] tipArray = {"A","B","C"};
DefaultComboBoxModel comboModel = new DefaultComboBoxModel(tipArray);
JComboBox ComboTipo = new JComboBox(comboModel);
mytable.getColumnModel().getColumn(0).setCellEditor(new DefaultCellEditor(ComboTipo));
