Question

Answer 1

Looking at the How to Use Tables tutorial, I see that you pass an array of data and an array of column names to the JTable constructor. If you only want two columns, these two arrays should reflect that. Here's the example code from the tutorial:

String[] columnNames = {"First Name",
                        "Last Name",
                        "Sport",
                        "# of Years",
                        "Vegetarian"};

Object[][] data = {
    {"Mary", "Campione",
     "Snowboarding", new Integer(5), new Boolean(false)},
    {"Alison", "Huml",
     "Rowing", new Integer(3), new Boolean(true)},
    {"Kathy", "Walrath",
     "Knitting", new Integer(2), new Boolean(false)},
    {"Sharon", "Zakhour",
     "Speed reading", new Integer(20), new Boolean(true)},
    {"Philip", "Milne",
     "Pool", new Integer(10), new Boolean(false)}
};

JTable table = new JTable(data, columnNames);

So in order to cut back to two columns, the columnNames array should have only two elements, and the two-dimensional data array should have only two columns.
