Constructor JTable(TableModel dm,TableColumnModel cm) doesn't work correctly.

The following commnet is from one of our customers :

> If you pass a TableColumnModel in the constructor to a JTable, along
> with
> the TableModel, the TableColumnModel's values are not used. Worse
> still,
> is the data in the TableColumnModel is destroyed. This is because the
> JTable
> defaults to:
>
> setAutoResizeMode(AUTO_RESIZE_ALL_COLUMNS);
> setAutoCreateColumnsFromModel(true);
>
> which destroys my TableColumnModel passed in the constructor.

I have verified it with swing-1.0 and provided the following test which can demostrate this bug :

import com.sun.java.swing.*;
import com.sun.java.swing.table.*;

import java.awt.*;
import java.awt.event.*;
import java.lang.*;

public class ColTest extends JPanel {

  JTable table;

  public static void main(String[] args)
  {
    JFrame frame = new JFrame("test") ;
    frame.getContentPane().setLayout(new BorderLayout()) ;
    ColTest panel = new ColTest() ;
    frame.getContentPane().add("Center",panel) ;
    frame.setBounds(0,0,640,480) ;
    frame.setVisible(true) ;
  }


  public ColTest() {
    super();
    setLayout(new BorderLayout());

    // final
    final String[] names = {"First Name", "Last Name", "Favorite Color",
                                "Favorite Sport", "Vegetarian"};

    // Create the dummy data (a few rows of names)
    final Object[][] data = {
    {"Mark", "Andrews", "red", "Baseball", new Boolean(true)},
    {"Tom", "Ball", "Blue", "Football", new Boolean(false)}
    };

    // Create a model of the data.
    TableModel dataModel = new AbstractTableModel() {
       public int getColumnCount() { return names.length; }
       public int getRowCount() { return data.length;}
       public Object getValueAt(int row, int col) {return data[row][col];}
       public String getColumnName(int column) {return names[column];}
    };
    TableColumnModel colModel = new DefaultTableColumnModel();
    colModel.setColumnMargin(100);
    System.out.println("setColumnMargin(100) before calling JTable(TableModel,
TableColumnModel)");

    table = new JTable(dataModel, colModel) ;

    System.out.println("After constructing JTable : getColumnMargin = " + table
.getColumnModel().getColumnMargin());


    JScrollPane scrollpane = JTable.createScrollPaneForTable(table);
    add(scrollpane, BorderLayout.CENTER);
    }
}
