Java程序从二维数组创建DefaultTableModel

Java Program to create DefaultTableModel from two dimensional array

DefaultTableModel是TableModel的实现，该实现使用Vector的Vector存储单元格值对象。首先，为行和列创建一个二维数组-

1

DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
{"India","Asia" }, {"Canada","North America" }, {"Singapore","Asia" },
{"Malaysia","Asia" }, {"Philippins","Asia" }, {"Oman","Asia" },
{"Germany","Europe" }, {"France","Europe" }
},
new Object[] {"Country","Continent" });

上面的"国家"和"大陆"是列。现在，将上述行和列设置为JTable-

1	JTable table = new JTable(tableModel);

以下是从二维数组创建DefaultTableModel的示例-

public class SwingDemo {
public static void main(String[] argv) throws Exception {
DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
{"India","Asia" }, {"Canada","North America" }, {"Singapore","Asia" },
{"Malaysia","Asia" }, {"Philippins","Asia" }, {"Oman","Asia" },
{"Germany","Europe" }, {"France","Europe" }
},
new Object[] {"Country","Continent" });
JTable table = new JTable(tableModel);
Font font = new Font("Verdana", Font.PLAIN, 12);
table.setFont(font);
table.setRowHeight(30);
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
frame.setVisible(true);
}
}
