我不明白prepareEditor是如何工作的，我无法使用prepareEditor中的Action设置prepareRenderer的可见性规则，正如我在附图中捕获的那样
第 1 行的规则按我的预期工作，如果未选择 JCheckBox（也使用 JTable 选择荧光笔），其他 TableCell 是不可见的，但如果我在第 1.st TableColumn 中选择 JCheckBox，则我无法仅显示规则+ Mail TableColumn，仅显示TableRow中的所有组件，我怎样才能实现这一点
import java.awt.Component;
import javax.swing.*;
import javax.swing.event.*;
import javax.swing.table.*;
public class TableWithCheckBoxOrBlank {
private Object[] columns = new Object[]{
"Select", "Name", "Rule", "Mail", "Include", "Phone"};
private Object[][] data = {
{false, "Bill", false, "Blabla@bla", false, "00 000 000"},
{false, "Edd", false, "Blabla@bla", false, "00 000 000"},
{false, "Paul", false, "Blabla@bla", false, "00 000 000"},
{false, "ZOO", false, "Blabla@bla", false, "00 000 000"}};
public void makeUI() {
DefaultTableModel model = new DefaultTableModel(data, columns) {
private static final long serialVersionUID = 1L;
@Override
public boolean isCellEditable(int row, int column) {
return column != 1;
}
@Override
public Class getColumnClass(int columnIndex) {
switch (columnIndex) {
case 0:
return Boolean.class;
case 1:
return String.class;
case 2:
return Boolean.class;
case 3:
return String.class;
case 4:
return Boolean.class;
case 5:
return String.class;
}
return null;
}
};
final JTable table = new JTable(model) {
private static final long serialVersionUID = 1L;
@Override
public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
Component c = super.prepareRenderer(renderer, row, column);
if (column == 0 || column == 1 || (Boolean) getValueAt(row, 0)) {
return c;
}
return Box.createRigidArea(c.getPreferredSize());
}
@Override
public Component prepareEditor(TableCellEditor editor, int row, int column) {
Component c = super.prepareEditor(editor, row, column);
if (column == 0 || column == 1 || (Boolean) getValueAt(row, 0)) {

}
return Box.createRigidArea(c.getPreferredSize());
}
};
model.addTableModelListener(new TableModelListener() {
@Override
public void tableChanged(TableModelEvent e) {
if (e.getColumn() == 0) {
if ((Boolean) table.getValueAt(table.getSelectedRow(), 0)) {
table.setValueAt(Boolean.FALSE, table.getSelectedRow(), 2);
}
table.repaint();
}
}

table.setPreferredScrollableViewportSize(table.getPreferredSize());

我觉得prepareRenderer(...)代码应该是：
public Component prepareRenderer(TableCellRenderer renderer, int row, int column) {
Component c = super.prepareRenderer(renderer, row, column);
if ((column == 2 || column == 3) && (Boolean)getValueAt(row, 0)) {
return c;
}
// if (column == 0 || column == 1 || (Boolean) getValueAt(row, 0)) {
if (column == 0 || column == 1) {
return c;
}
return Box.createRigidArea(c.getPreferredSize());
}
那么你应该摆脱prepareEditor(...)代码。相反，你应该有更多的逻辑isCellEditable(...)方法。就像是：
public boolean isCellEditable(int row, int column) {
if (column == 0) return true;
if (column == 1 || column == 4 || column == 5) return false;
return (Boolean)getValueAt(row, 0);
}
