我在 Java Swing 中有一个 JTable。我需要设置字体大小、颜色和样式。我如何在 JTable 中实现它?

最佳答案

为什么在 JTable 中将 TableRenderer 设置为基本设置, 更多 --> JTable#setWhatever

enter image description here

编辑(移除镇流器)代码:

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

public class TableExample {

public TableExample() {
Object[][] data1 = new Object[50][5];
for (int i = 0; i < data1.length; i++) {
data1[i][0] = "Company # " + (i + 1);
for (int j = 1; j < data1[i].length; j++) {
data1[i][j] = "" + (i + 1) + ", " + j;
}
}
String[] headers = {"Col 1", "Col 2", "Col 3", "Col 4", "Col 5"};
DefaultTableModel model1 = new DefaultTableModel(data1, headers);
final JTable jTable1 = new JTable(model1);
jTable1.setBackground(Color.orange);
jTable1.setForeground(Color.blue);
jTable1.setRowHeight(24);
jTable1.setFont(new Font("Arial", Font.BOLD, 12));
jTable1.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
final JScrollPane sp1 = new JScrollPane();
sp1.setPreferredSize(new Dimension(600, 200));
sp1.setViewportView(jTable1);
final JTable jTable2 = new JTable(model1);
jTable2.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
final JScrollPane sp2 = new JScrollPane();
sp2.setPreferredSize(new Dimension(600, 200));
sp2.setViewportView(jTable2);
final JTable jTable3 = new TableBackroundPaint0(data1, headers);
jTable3.setSelectionMode(ListSelectionModel.SINGLE_SELECTION);
jTable3.setModel(model1);
final JScrollPane sp3 = new JScrollPane();
sp3.setPreferredSize(new Dimension(600, 200));
sp3.setViewportView(jTable3);
JPanel panel1 = new JPanel();
panel1.setLayout(new GridLayout(3, 0, 10, 10));
panel1.add(sp1);
panel1.add(sp2);
panel1.add(sp3);
JFrame frame = new JFrame("tableSelection");
frame.add(panel1);
frame.pack();
frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
frame.setVisible(true);
}

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

@Override
public void run() {
TableExample te = new TableExample();
}
});
}
}

class TableBackroundPaint0 extends JTable {

private static final long serialVersionUID = 1L;

TableBackroundPaint0(Object[][] data, Object[] head) {
super(data, head);
setOpaque(false);
((JComponent) getDefaultRenderer(Object.class)).setOpaque(false);
}

@Override
public void paintComponent(Graphics g) {
Color background = new Color(168, 210, 241);
Color controlColor = new Color(230, 240, 230);
int width = getWidth();
int height = getHeight();
Graphics2D g2 = (Graphics2D) g;
Paint oldPaint = g2.getPaint();
g2.setPaint(new GradientPaint(0, 0, background, width, 0, controlColor));
g2.fillRect(0, 0, width, height);
g2.setPaint(oldPaint);
for (int row : getSelectedRows()) {
Rectangle start = getCellRect(row, 0, true);
Rectangle end = getCellRect(row, getColumnCount() - 1, true);
g2.setPaint(new GradientPaint(start.x, 0, controlColor, (int) ((end.x + end.width - start.x) * 1.25), 0, Color.orange));
g2.fillRect(start.x, start.y, end.x + end.width - start.x, start.height);
}
super.paintComponent(g);
}
}
