Hiding column headers

import java.awt.BorderLayout; import javax.swing.JFrame; import javax.swing.JScrollPane; import javax.swing.JTable; public class NullColumnHeader {   public static void main(String args[]) {     JFrame frame = new JFrame();     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);     Object rowData[][] = { { "Row1-Column1", "Row1-Column2", "Row1-Column3" },         { "Row2-Column1", "Row2-Column2", "Row2-Column3" } };     Object columnNames[] = { "1", "2", "3" };     JTable table = new JTable(rowData, columnNames);     JScrollPane scrollPane = new JScrollPane(table);     table.setTableHeader(null);          frame.add(scrollPane, BorderLayout.CENTER);     frame.setSize(300, 150);     frame.setVisible(true);   } } You could also remove headers by subclassing JTable and overriding the protected configureEnclosingScrollPane() method, or by telling every TableColumn that its header value is empty.
