如何从jtable中删除一行

我想更改按钮的操作以删除。我有这个代码：
package buttonexample; import java.awt.BorderLayout; import java.awt.Component; import java.awt.Dimension; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import javax.swing.*; import javax.swing.table.AbstractTableModel; import javax.swing.table.DefaultTableModel; import javax.swing.table.TableCellRenderer; import javax.swing.table.TableModel; public class ButtonExample { public JTable table; public static void main(String[] args) { final ButtonExample example = new ButtonExample(); javax.swing.SwingUtilities.invokeLater(new Runnable() { public void run() { example.createAndShowGUI(); } }); } private void createAndShowGUI() { JFrame frame = new JFrame("Button Example"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); table = new JTable(new JTableModel()); JScrollPane scrollPane = new JScrollPane(table); table.setFillsViewportHeight(true); TableCellRenderer buttonRenderer = new JTableButtonRenderer(); //table.getColumn("Button1").setCellRenderer(buttonRenderer); table.getColumn("Button2").setCellRenderer(buttonRenderer); table.addMouseListener(new JTableButtonMouseListener(table)); frame.getContentPane().add(scrollPane, BorderLayout.CENTER); frame.getContentPane().setPreferredSize(new Dimension(500, 200)); frame.pack(); frame.setVisible(true); } public static class JTableModel extends AbstractTableModel { private static final long serialVersionUID = 1L; private static final String[] COLUMN_NAMES = new String[] {"Id", "Stuff", "Asdfsdf", "Button2"}; private static final Class[] COLUMN_TYPES = new Class[] {Integer.class, String.class, String.class, JButton.class}; @Override public int getColumnCount() { return COLUMN_NAMES.length; } @Override public int getRowCount() { return 4; } @Override public String getColumnName(int columnIndex) { return COLUMN_NAMES[columnIndex]; } @Override public Class getColumnClass(int columnIndex) { return COLUMN_TYPES[columnIndex]; } @Override public Object getValueAt(final int rowIndex, final int columnIndex) { switch (columnIndex) { case 0: return rowIndex; case 1: return "Text for "+rowIndex; case 2: return "Column for "+rowIndex; case 3: final JButton button = new JButton(COLUMN_NAMES[columnIndex]); button.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent arg0) { // When this is clicked the whole row will be deleted. JOptionPane.showMessageDialog(JOptionPane.getFrameForComponent(button), "Button clicked for row "+rowIndex); } }); return button; default: return "Error"; } } } private static class JTableButtonRenderer implements TableCellRenderer { @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { JButton button = (JButton)value; if (isSelected) { button.setForeground(table.getSelectionForeground()); button.setBackground(table.getSelectionBackground()); } else { button.setForeground(table.getForeground()); button.setBackground(UIManager.getColor("Button.background")); } return button; } } private static class JTableButtonMouseListener extends MouseAdapter { private final JTable table; public JTableButtonMouseListener(JTable table) { this.table = table; } public void mouseClicked(MouseEvent e) { int column = table.getColumnModel().getColumnIndexAtX(e.getX()); int row = e.getY()/table.getRowHeight(); if (row = 0 && column 
= 0) { Object value = table.getValueAt(row, column); if (value instanceof JButton) { ((JButton)value).doClick(); } } } } } 但是(DefaultTableModel)someTable.getModel(); model.removeRow(row); (DefaultTableModel)someTable.getModel(); model.removeRow(row); 我无法使它工作，因为表模型没有任何名称，我不知道该命名。 我已经尝试初始化表模型，我得到错误说非静态变量模型不能引用静态上下文。 有没有办法删除静态上下文中的行？

 渲染单元格是视图的领域 
 模型应该永远不会包含组件，特别是如果你正在考虑将它们渲染到屏幕上，这只是错误的方法…… 
 您需要设置一个TableCellEditor ，它将作为您检索编辑操作通知的手段（鼠标单击或按键） 

 这是一个基本的例子，为了简单起见，我使用了DefaultTableModel因为它有一个很好的removeRow方法，但可以想象，你可以使用任何TableModel ，只要你提供了删除行并由编辑器修改以支持的方法。它…

 仔细查看如何使用表格了解更多详情 
 这只是个人偏好，但我更喜欢使用工具栏或菜单项和键绑定来提供此支持。 表中的按钮看起来如此......过时了 - 恕我直言
