带有标题行和列的JTable

我怎么能有一个JTable与列和行都有标题？
像这样的东西：

+------+------+------+------+ |/\/\/\| col1 | col2 | col3 | +------+------+------+------+ | row1 | | | | +------+------+------+------+ | row2 | | | | +------+------+------+------+ | row3 | | | | +------+------+------+------+ 

谢谢

我认为你在searchRowTable

 import java.awt.*; import java.awt.event.ActionEvent; import javax.swing.*; import javax.swing.UIManager.*; import javax.swing.event.*; import javax.swing.table.*; public class JTableRowHeader { private JFrame frame = new JFrame("JTable RowHeader"); private JScrollPane scrollPane; private JTable table; private DefaultTableModel model; private TableRowSorter<TableModel> sorter; private JTable headerTable; public JTableRowHeader() { table = new JTable(4, 4); for (int i = 0; i < table.getRowCount(); i++) { table.setValueAt(i, i, 0); } sorter = new TableRowSorter<TableModel>(table.getModel()); table.setRowSorter(sorter); model = new DefaultTableModel() { private static final long serialVersionUID = 1L; @Override public int getColumnCount() { return 1; } @Override public boolean isCellEditable(int row, int col) { return false; } @Override public int getRowCount() { return table.getRowCount(); } @Override public Class<?> getColumnClass(int colNum) { switch (colNum) { case 0: return String.class; default: return super.getColumnClass(colNum); } } }; headerTable = new JTable(model); for (int i = 0; i < table.getRowCount(); i++) { headerTable.setValueAt("Row " + (i + 1), i, 0); } headerTable.setShowGrid(false); headerTable.setAutoResizeMode(JTable.AUTO_RESIZE_OFF); headerTable.setPreferredScrollableViewportSize(new Dimension(50, 0)); headerTable.getColumnModel().getColumn(0).setPreferredWidth(50); headerTable.getColumnModel().getColumn(0).setCellRenderer(new TableCellRenderer() { @Override public Component getTableCellRendererComponent(JTable x, Object value, boolean isSelected, boolean hasFocus, int row, int column) { boolean selected = table.getSelectionModel().isSelectedIndex(row); Component component = table.getTableHeader().getDefaultRenderer().getTableCellRendererComponent(table, value, false, false, -1, -2); ((JLabel) component).setHorizontalAlignment(SwingConstants.CENTER); if (selected) { component.setFont(component.getFont().deriveFont(Font.BOLD)); component.setForeground(Color.red); } else { component.setFont(component.getFont().deriveFont(Font.PLAIN)); } return component; } }); table.getRowSorter().addRowSorterListener(new RowSorterListener() { @Override public void sorterChanged(RowSorterEvent e) { model.fireTableDataChanged(); } }); table.getSelectionModel().addListSelectionListener(new ListSelectionListener() { @Override public void valueChanged(ListSelectionEvent e) { model.fireTableRowsUpdated(0, model.getRowCount() - 1); } }); scrollPane = new JScrollPane(table); scrollPane.setRowHeaderView(headerTable); table.setPreferredScrollableViewportSize(table.getPreferredSize()); frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE); frame.add(scrollPane); frame.add(new JButton(new AbstractAction("Toggle filter") { private static final long serialVersionUID = 1L; private RowFilter<TableModel, Object> filter = new RowFilter<TableModel, Object>() { @Override public boolean include(javax.swing.RowFilter.Entry<? extends TableModel, ? extends Object> entry) { return ((Number) entry.getValue(0)).intValue() % 2 == 0; } }; @Override public void actionPerformed(ActionEvent e) { if (sorter.getRowFilter() != null) { sorter.setRowFilter(null); } else { sorter.setRowFilter(filter); } } }), BorderLayout.SOUTH); frame.pack(); frame.setLocation(150, 150); frame.setVisible(true); } public static void main(String[] args) { try {// UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName()); for (LookAndFeelInfo info : UIManager.getInstalledLookAndFeels()) { if (info.getName().equals("Nimbus")) { UIManager.setLookAndFeel(info.getClassName()); break; } } } catch (Exception e) { //e.printStackTrace(); } EventQueue.invokeLater(new Runnable() { @Override public void run() { JTableRowHeader TestTableRowHeader = new JTableRowHeader(); } }); } }

行标题和表值在mKorbel的解决scheme中不同步。 该表显示第1行和第2行，而不是第1行和第3行进行过滤。

这是一个基于他的例子的解决scheme。 它将行标题复制到表中的新列中，隐藏此列并在过滤时将值复制到另一列。

它工作，这是丑陋的，我们需要一个更好的解决scheme:)
