如何使用我自己的列名在JTable中显示MS Access DB？

Question

我试图向JTable输入一个表，但没有使用Vector（），因为它需要我在DB（短名称）中输入的列名，现在我想更改列名称，但是我没有了解如何做到这一点。

JTable table = new JTable(data, columNames); 
/* 
can use if both are Vectors, but I have to change columnNames with String[] columnNames  
*/

看到JTableHeader.setColumnModel(TableColumnModel columnModel)

例如

import java.awt.Dimension; 
import javax.swing.JFrame; 
import javax.swing.JScrollPane; 
import javax.swing.JTable; 
import javax.swing.ListSelectionModel; 
import javax.swing.SwingUtilities; 
import javax.swing.table.DefaultTableColumnModel; 
import javax.swing.table.TableColumn; 

public class TablePreferredSize { 

    private String[] head = {"One", "Two", "Three", "Four", "Five", "Six"}; 
    private String[][] data = new String[25][6]; 
    private JTable table = new JTable(data, head); 
    private DefaultTableColumnModel columnModel = new DefaultTableColumnModel(); 
    private TableColumn column = new TableColumn(); 

    public TablePreferredSize() { 
     table.setRowHeight(23); 
     table.setIntercellSpacing(new Dimension(1, 1)); 
     table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); 
     table.setSelectionMode(ListSelectionModel.SINGLE_SELECTION); 
     column = new TableColumn(); 
     column.setModelIndex(0); 
     column.setHeaderValue("apple"); 
     columnModel.addColumn(column); 
     column = new TableColumn(); 
     column.setModelIndex(1); 
     column.setHeaderValue("banana"); 
     columnModel.addColumn(column); 
     column = new TableColumn(); 
     column.setModelIndex(2); 
     column.setHeaderValue("pear"); 
     columnModel.addColumn(column); 
     column = new TableColumn(); 
     column.setModelIndex(3); 
     column.setHeaderValue("cherry"); 
     columnModel.addColumn(column); 
     column = new TableColumn(); 
     column.setModelIndex(4); 
     column.setHeaderValue("orange"); 
     columnModel.addColumn(column); 
     column = new TableColumn(); 
     column.setModelIndex(5); 
     column.setHeaderValue("lemon"); 
     columnModel.addColumn(column); 
     table.setColumnModel(columnModel); 
     //table.setPreferredScrollableViewportSize(new Dimension(rowWidth, 12 * rowHeight)); 
     JScrollPane scrollPane = new JScrollPane(table); 
     JFrame frame = new JFrame("Table PreferredSize"); 
     frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); 
     frame.add(scrollPane); 
     frame.pack(); 
     frame.setVisible(true); 
    } 

    public static void main(String[] args) { 
     SwingUtilities.invokeLater(new Runnable() { 

      @Override 
      public void run() { 
       TablePreferredSize t = new TablePreferredSize(); 
      } 
     }); 
    } 
}
