jtableheader

I have just started working with JTable . This is my table example. The add row button adds rows to the table. I want to create row headers for this table. How can I achieve this? Can any one help me please? The code for the sample table is: package test; import javax.swing.*; import java.awt.*; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.ItemEvent; import java.awt.event.ItemListener; import javax.swing.table.*; import test.InsertRows.CellEditor; public class SampleTable extends JFrame { JTable table; JPanel panel; DefaultTableModel dataModel;

The color of the header in my project is shining in a different way. In the examples where the color change works, I see different graphics. EDIT 2: Something else. I noticed that the buttons won't change color either. Must be something generic. Hope this helps. Unfortunately SSCCE won

I'm trying to put background color on the JTable header but it seems that it doesnt change the header's color this is my code for my JTable.. what am I doing wrong? Color headerColor = new Color(25, 78, 132); itemTable = new JTable(){ public boolean isCellEditable(int row, int column) { return false; }; Color rowColor1 = new Color(99, 154, 206); Color rowColor2 = new Color(148, 186, 231); public Component prepareRenderer(TableCellRenderer renderer, int row, int column) { Component stamp = super.prepareRenderer(renderer, row, column); if (row % 2 == 0) stamp.setBackground(rowColor1); else stamp
