尝试文档：

https://docs.oracle.com/javase/tutorial/uiswing/components/table.html

这是建议的方法之一：

// The table in SimpleTableDemo.java declares the column names in a String array:

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

// Its data is initialized and stored in a two-dimensional Object array:

Object[][] data = {
    {"Kathy", "Smith",
     "Snowboarding", new Integer(5), new Boolean(false)},
    {"John", "Doe",
     "Rowing", new Integer(3), new Boolean(true)},
    {"Sue", "Black",
     "Knitting", new Integer(2), new Boolean(false)},
    {"Jane", "White",
     "Speed reading", new Integer(20), new Boolean(true)},
    {"Joe", "Brown",
     "Pool", new Integer(10), new Boolean(false)}
};

// Then the Table is constructed using these data and columnNames:

JTable table = new JTable(data, columnNames);
