How to disable JTable Column Dragging (only single column)

Question

How could i disable a single column from being dragged in JTable?
I need to fix the first column from being dragged in JTable and all other columns except the first can be dragged. how would i accomplish this task ?
well, i know how to fix all column in jtable from being dragged using
table.getTableHeader().setReorderingAllowed(false);But dont know how to fix only a single column. is there any method for doing this. or i have to implement any other logic?
Please help me !
Thanks

Answer 1

The question is why do you have this requirement. I figure if the user wants to reorder the colum, let them, the table won't break.
Maybe something like this would be acceptable:
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class FixedColumnScrollPane extends JScrollPane
    public FixedColumnScrollPane(JTable main, int fixedColumns)
        super( main );
        //  Use the table to create a new table sharing
        //  the DataModel and ListSelectionModel
        JTable fixed = new JTable( main.getModel() );
        fixed.setFocusable( false );
        fixed.setSelectionModel( main.getSelectionModel() );
        fixed.getTableHeader().setReorderingAllowed( false );
//        fixed.getTableHeader().setResizingAllowed( false );
        fixed.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
        main.putClientProperty("terminateEditOnFocusLost", Boolean.TRUE);
        //  Remove the fixed columns from the main table
        for (int i = 0; i < fixedColumns; i++)
            TableColumnModel columnModel = main.getColumnModel();
            columnModel.removeColumn( columnModel.getColumn( 0 ) );
        //  Remove the non-fixed columns from the fixed table
        while (fixed.getColumnCount() > fixedColumns)
            TableColumnModel columnModel = fixed.getColumnModel();
            columnModel.removeColumn( columnModel.getColumn( fixedColumns ) );
        //  Add the fixed table to the scroll pane
        fixed.setPreferredScrollableViewportSize(fixed.getPreferredSize());
        setRowHeaderView( fixed );
        setCorner(JScrollPane.UPPER_LEFT_CORNER, fixed.getTableHeader());
    public static void main(String[] args)
        //  Build your table normally
        JTable table = new JTable(10, 8);
        table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
        JScrollPane scrollPane= new FixedColumnScrollPane(table, 1 );
        JFrame frame = new JFrame("Table Fixed Column Demo");
        frame.setDefaultCloseOperation( JFrame.EXIT_ON_CLOSE );
        frame.getContentPane().add( scrollPane );
        frame.setSize(400, 300);
        frame.setVisible(true);
}Or maybe you should be using a Row Header. A row header is like the column header of JTable. It remains fixed on the left side of the scroll pane. Search the forum for examples using "setrowheaderview".
