如何在 Java 中从二维数组创建 JTable?


对于二维数组,设置一个表的列。此外,我们已经使用一个一维数组设置了行,如下所示 −

DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
   { "Mobile Phones", "100" }, { "RAM", "200" }, { "Caps", "50" },
   { "Tablet", "80" }, { "LED", "400" }, { "Trousers", "350" },
   { "T-Shirt", "500" }, { "Hoodie", "650" }, { "Jeans", "900" } },
   new Object[] { "Items", "Quantity" }
);

现在,设置表的模型 −

JTable table = new JTable(tableModel);

下面是通过二维数组创建表的示例 −

示例

package my;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
   public static void main(String[] argv) throws Exception {
      DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
         { "Mobile Phones", "100" }, { "RAM", "200" }, { "Caps", "50" },
         { "Tablet", "80" }, { "LED", "400" }, { "Trousers", "350" },
         { "T-Shirt", "500" }, { "Hoodie", "650" }, { "Jeans", "900" } },
         new Object[] { "Items", "Quantity" }
      );
      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);
   }
}

这将产生以下输出 −
