在java中设置JTable中行的高度 [英] Setting the height of a row in a JTable in java

问题描述

我一直在寻找能够增加JTable中行高的解决方案。我一直在使用setRowHeight（int int）方法编译并运行OK，但没有增加row [s]。当我使用行的getRowHeight（int）方法设置高度时，它会打印出我将行增加到的大小，所以我不确定是什么问题。下面的代码粗略说明了我是如何解决它的。

I have been searching for a solution to be able to increase the height of a row in a JTable. I have been using the setRowHeight(int int) method which compiles and runs OK, but no row[s] have been increased. When I use the getRowHeight(int) method of the row I set the height to, it does print out the size I increased the row to, so I'm not sure what is wrong. The code below is a rough illustration how I am trying to solve it.

我的类扩展了JFrame。

My class extends JFrame.

String[] columnNames = {"Column 1", "Column 2", "Column 1 3"};

JTable table = new JTable(new DefaultTableModel(columnNames, people.size()));

DefaultTableModel model = (DefaultTableModel) table.getModel();

int count =1;
for(Person p: people)
{
    model.insertRow(count,(new Object[]{count, p.getName(), p.getAge()+"", 
    p.getNationality}));
    count++;
}

table.setRowHeight(1, 15);//Try set height to 15 (I've tried higher)

谁能告诉我哪里出错了？我试图将第1行的高度增加到15像素？

Can anyone tell me where I am going wrong? I am trying to increase the height of row 1 to 15 pixels?

推荐答案

不确定离开第一行的意图是什么在索引0为空。 JTable 中的行从索引0开始运行。最好能够发布一个完整的示例（即 SSCCE ）展示了这些问题。比较这个工作正常的简单例子：

Not sure what is the intention of leaving the first row at index 0 empty. Rows in JTable run from index 0. It is best if you could post a complete example (ie SSCCE) that demonstrates the issues. Compare to this simple example that works OK:

import javax.swing.*;
import javax.swing.table.DefaultTableModel;

public class DemoTable {
    private static void createAndShowGUI() {
        JFrame frame = new JFrame("DemoTable");
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

        DefaultTableModel model = new DefaultTableModel();
        model.setColumnIdentifiers(new Object[] {
                "Column 1", "Column 2", "Column 3" });

        JTable table = new JTable(model);
        for (int count = 0; count < 3; count++){
            model.insertRow(count, new Object[] { count, "name", "age"});
        }
        table.setRowHeight(1, 30);

        frame.add(new JScrollPane(table));
        frame.setLocationByPlatform(true);
        frame.pack();
        frame.setVisible(true);
    }

    public static void main(String args[]) {
        SwingUtilities.invokeLater(new Runnable() {
            public void run() {
                createAndShowGUI();
            }
        });
    }
}
