    Hi. I'm using JTable with DefaultTableModel. How do you change the width of some specific columns? Thank you.

    Default Re: JTable

    [code=Java]
    // Packages to import
    import javax.swing.JFrame;
    import javax.swing.JScrollPane;
    import javax.swing.JTable;

    public class JTableExamples {
    // frame
    JFrame f;
    // Table
    JTable j;

    // Constructor
    JTableExamples()
    {
    // Frame initialization
    f = new JFrame();

    // Frame Title
    f.setTitle("JTable Example");

    // Data to be displayed in the JTable
    String[][] data = {
    { "Kundan Kumar Jha", "4031", "CSE" },
    { "Anand Jha", "6014", "IT" }
    };

    // Column Names
    String[] columnNames = { "Name", "Roll Number", "Department" };

    // Initializing the JTable
    j = new JTable(data, columnNames);
    j.setBounds(30, 40, 200, 300);

    // adding it to JScrollPane
    JScrollPane sp = new JScrollPane(j);
    f.add(sp);
    // Frame Size
    f.setSize(500, 200);
    // Frame Visible = true
    f.setVisible(true);
    }

    // Driver method
    public static void main(String[] args)
    {
    new JTableExamples();
    }
    }

    [code]

    j.setBounds(x,y,x,y) // you can see that the boundary of the table already automatically adjust the table to your liking. Whatever you type in. This is a program that makes this table. Okay. But you know how a Java printout looks like right?
