Java Program to change the background color of rows in a JTable
To change the background color of rows, you need to use the setBackground() method −
JTable table = new JTable(marks, col); table.setBackground(Color.blue);
Above, we have set the color using Color class −
Color.blue
The following is an example to change the background color of rows −
Example
package my;
import java.awt.Color;
import java.awt.Font;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
Integer[][] marks = {
{ 70, 66, 76, 89, 67, 98 },
{ 67, 89, 64, 78, 59, 78 },
{ 68, 87, 71, 65, 87, 86 },
{ 80, 56, 89, 98, 59, 56 },
{ 75, 95, 90, 73, 57, 79 },
{ 69, 49, 56, 78, 76, 77 }
};
String col[] = { "S1", "S2", "S3", "S4", "S5", "S6"};
JTable table = new JTable(marks, col);
Font font = new Font("Verdana", Font.PLAIN, 12);
table.setFont(font);
table.setRowHeight(30);
table.setBackground(Color.blue);
table.setForeground(Color.white);
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
frame.setVisible(true);
}
}Output
