Horizontal Scroll in JTable

Question

Hello!
I have a JTable inside a JScrollPane when the table has horizontal scroll it looks strange. When the user clicks in arrows of horizontal scroll the headers of table don't follow the scroll.
What am I doing wrong?
Thanks,
Pati

Answer 1

That's my code
import java.awt.Dimension;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class Teste extends JFrame{
     public Teste()
     this.setSize(320,270);
     JTable table = new JTable(10,15);
     JScrollPane scroll = new JScrollPane(table, JScrollPane.VERTICAL_SCROLLBAR_NEVER, JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
     table.getColumnModel().getColumn(0).setPreferredWidth(150);
     table.getTableHeader().setPreferredSize(new Dimension(150,15));
     table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
     scroll.setBounds(10,10,300,250);
     this.getContentPane().add(scroll);
     this.setVisible(true);
     public static void main(String args[]){
          Teste obj = new Teste();          
The problem is in line:
table.getTableHeader().setPreferredSize(new Dimension(150,15));
When I remove it, the table works well.
