Java 程序在 JTable 中设置多行不同高度


要设置多行不同高度,请针对想要增大行高的不同行使用 setRowHeight() 方法。我们首先看一个创建表格的示例,所有行的行高相同 −

示例

package my;
import java.awt.Color;
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();
      JTable table = new JTable(tableModel);
      tableModel.addColumn("Language/ Technology");
      tableModel.addColumn("Text Tutorial");
      tableModel.addColumn("Video Tutorial");
      tableModel.addColumn("Interview QA");
      tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "C#", "Yes", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "Java", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "MVC", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "F#", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "AWS", "No", "No", "Yes"});
      table.setBackground(Color.orange);
      table.setForeground(Color.black);
      Font font = new Font("Verdana", Font.CENTER_BASELINE, 12);
      table.setFont(font);
      JFrame frame = new JFrame();
      frame.setSize(600, 400);
      frame.add(new JScrollPane(table));
      frame.setVisible(true);
   }
}

输出如下,显示所有行高度相同。这是所有行的默认值 −

现在,我们来看一个设置多行不同高度的示例。在此,我们使用 setRowHeight() 方法多次,从而为不同行赋予不同高度 −

示例

package my;
import java.awt.Color;
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();
      JTable table = new JTable(tableModel);
      tableModel.addColumn("Language/ Technology");
      tableModel.addColumn("Text Tutorial");
      tableModel.addColumn("Video Tutorial");
      tableModel.addColumn("Interview QA");
      tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "C#", "Yes", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "Java", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "MVC", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "F#", "Yes", "No", "Yes"});
      tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "Yes"});
      tableModel.addRow(new Object[] { "AWS", "No", "No", "Yes"});
      // set different height for different rows
      table.setRowHeight(2, 50);
      table.setRowHeight(4, 35);
      table.setRowHeight(6, 20);
      table.setRowHeight(8, 45);
      table.setBackground(Color.orange);
      table.setForeground(Color.black);
      Font font = new Font("Verdana", Font.CENTER_BASELINE, 12);
      table.setFont(font);
      JFrame frame = new JFrame();
      frame.setSize(600, 400);
      frame.add(new JScrollPane(table));
      frame.setVisible(true);
   }
}

输出如下,显示不同高度的行 −
