JTable without a header
提问by saurabh
Can anyone tell me how to create a table without a table header?
谁能告诉我如何创建没有表头的表？
I am making Sudoku puzzle and I want to create a table without the table header in Java. Is it possible?
我正在制作数独谜题，我想在 Java 中创建一个没有表头的表。是否可以？
回答by Peter Lang
I don't think that you want your Sudoku to scroll, so the easiest way should be notto put your table into a JScrollPane, which is responsible for displaying the header:
我不认为您希望您的数独滚动，因此最简单的方法应该是不要将您的表格放入 a JScrollPane，它负责显示标题：
The other way is to call
另一种方式是调用
table.setTableHeader(null);
回答by Ray Hulha
So the trick seems to be to first set a header using the DefaultTableModel constructor but then later to call setTableHeader(null);
所以诀窍似乎是首先使用 DefaultTableModel 构造函数设置标题，然后再调用 setTableHeader(null);
Here is some demo code:
这是一些演示代码：
package net.raysforge.visual.demo;
import java.awt.BorderLayout;
import java.awt.EventQueue;
import java.awt.GridBagConstraints;
import java.awt.GridBagLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class JTableAndGBC {
private String[] columnNames = {"Source", "Hit", "Last", "Ur_Diff"};
private JTable table;
private Object[][] data = {{"Swing Timer", 2.99, 5, 1.01},
{"Swing Worker", 7.10, 5, 1.010}, {"TableModelListener", 25.05, 5, 1.01}};
private DefaultTableModel model = new DefaultTableModel(data, columnNames);
public JTableAndGBC() {
JPanel panel = new JPanel(new GridBagLayout());
table = new JTable(model);
GridBagConstraints gbc = new GridBagConstraints();
gbc.weightx = 1.0;
gbc.fill = GridBagConstraints.HORIZONTAL;
JScrollPane pane = new JScrollPane(table);
table.setPreferredScrollableViewportSize(table.getPreferredSize());
table.setTableHeader(null);
panel.add(pane, gbc);
JFrame frame = new JFrame();
frame.add(panel, BorderLayout.CENTER);
frame.pack();
frame.setVisible(true);
}
public static void main(String args[]) throws Exception {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
new JTableAndGBC();
}
});
}
}

Anyone having problems with the suggested methods, try the following:
任何对建议的方法有问题的人，请尝试以下操作：
jTable.getTableHeader().setUI(null);
This is tested with Java 8.
这是用 Java 8 测试的。
