如何直接从数据库中将数据填充到Jtable
我显示Jtable取决于数据库中的特定列，我的jtable中的最后两列是图像字段。如何动态更改列而不影响最后两列。请指教我如何做。
使用java.util.Collection Vector
请参阅 http://www.roseindia.com上的 此示例
import java.sql.*; import java.util.*; import javax.swing.*; import javax.swing.table.TableColumn; public class JTableResultSet { public static void main(String[] args) { Vector columnNames = new Vector(); Vector data = new Vector(); JPanel panel = new JPanel(); // try { Class.forName("com.mysql.jdbc.Driver").newInstance(); Connection con = DriverManager.getConnection( "jdbc:mysql://localhost:3306/test", "root", "root"); String sql = "Select name,address from user"; Statement statement = con.createStatement(); ResultSet resultSet = statement.executeQuery(sql); ResultSetMetaData metaData = resultSet.getMetaData(); int columns = metaData.getColumnCount(); for (int i = 1; i <= columns; i++) { columnNames.addElement(metaData.getColumnName(i)); } while (resultSet.next()) { Vector row = new Vector(columns); for (int i = 1; i <= columns; i++) { row.addElement(resultSet.getObject(i)); } data.addElement(row); } resultSet.close(); statement.close(); } catch (Exception e) { System.out.println(e); } JTable table = new JTable(data, columnNames); TableColumn column; for (int i = 0; i < table.getColumnCount(); i++) { column = table.getColumnModel().getColumn(i); column.setMaxWidth(250); } JScrollPane scrollPane = new JScrollPane(table); panel.add(scrollPane); JFrame frame = new JFrame(); frame.add(panel); //adding panel to the frame frame.setSize(600, 400); //setting frame size frame.setVisible(true); //setting visibility true } }
TableModel.setValueAt(Objet value, int row, int col)
