I notice. That code was also a very good description
of the *immediate* problem of the table header not
appearing (that is the current problem, right?).

You are going to swear when you see how close you
were to seeing that header.. ;)

<sscce>
import java.awt.*;
import javax.swing.*;

public class TableColumHeaderTest extends JFrame{
    public TableColumHeaderTest() {
        // I have to call this - matter of habit..
        setDefaultCloseOperation( JFrame.DISPOSE_ON_CLOSE );
        setLayout(new BorderLayout());
        Object[][] headerData = {{"H1","H2"},{"H3","H4"}};
        Object[][] dataData = {{"D1","D2"},{"D3","D4"}};
        Object[] tempHead = {"th","th"};
        JTable headerTable = new JTable(headerData,tempHead);
        JTable dataTable = new JTable(dataData,tempHead);
        // it is rarely necessary to call setVisible()!
        // (excepting root components)
        //dataTable.getTableHeader().setVisible(false);
        JScrollPane scrollPane = new JScrollPane(dataTable);
        scrollPane.setColumnHeaderView(headerTable);
        scrollPane.setCorner(JScrollPane.UPPER_LEFT_CORNER,
headerTable);
        getContentPane().add(BorderLayout.CENTER, scrollPane);
        pack();
    }

    public static void main(String[] args){
        TableColumHeaderTest t = new TableColumHeaderTest();
        t.setSize(400,300);
        t.setVisible(true);
    }
}
</sscce>
