How to fix cursor type or prevent it from changing

Question

I am working on a Jtable and I fixed the columns widths using:

colModel.getColumn(0).setMinWidth(15); colModel.getColumn(0).setMaxWidth(15); colModel.getColumn(0).setPreferredWidth(15);

but even so when hovering over the table edges/borders the double sided arrow cursos appears as if prompting the user to expand the columns. I want either to have the cursor type fixed throughout the whole dialog or prevent it from changing into this cursor in this specific instance.

It seems to be fine to use TableColumn#setResizable(false) method together.

import java.awt.*;
import javax.swing.*;
import javax.swing.table.*;

public class ResizeCursorTest {
  public JComponent makeUI() {
    JTable table = new JTable(new DefaultTableModel(10, 3));

    TableColumnModel colModel = table.getColumnModel();
    colModel.getColumn(0).setMinWidth(15);
    colModel.getColumn(0).setMaxWidth(15);
    colModel.getColumn(0).setPreferredWidth(15);
    colModel.getColumn(0).setResizable(false);

    JPanel p = new JPanel(new BorderLayout());
    p.add(new JScrollPane(table));
    return p;
  }
  public static void main(String... args) {
    EventQueue.invokeLater(() -> {
      JFrame f = new JFrame();
      f.setDefaultCloseOperation(WindowConstants.EXIT_ON_CLOSE);
      f.getContentPane().add(new ResizeCursorTest().makeUI());
      f.setSize(320, 240);
      f.setLocationRelativeTo(null);
      f.setVisible(true);
    });
  }
}
