How to change header background color of a table in Java

To change header background color, at first get the header background −

JTableHeader tableHeader = table.getTableHeader();

Now, set the background color using set Background() −

tableHeader.setBackground(Color.black);

Above, we have used the Color class to set the color.

The following is an example to change the header background color of a JTable −

Example

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.JTableHeader; 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);       JTableHeader tableHeader = table.getTableHeader();       tableHeader.setBackground(Color.black);       tableHeader.setForeground(Color.white);       JFrame frame = new JFrame();       frame.setSize(600, 400);       frame.add(new JScrollPane(table));       frame.setVisible(true);    } }

The output is as follows. Here, we have changed the header background color to BLACK −
