在 Java 中设置表格模型中的单元格是否可以被选中或取消选中?
java 8object oriented programmingprogramming更新于 2025/9/1 13:00:17
我们可以使用 setCellSelectionEnabled() 设置或禁止选中表格中的单元格。以下是示例。−
如果要允许选中单元格，请将方法设置为 TRUE −
table.setCellSelectionEnabled(true);
如果要禁止选中单元格，请将方法设置为 FALSE −
table.setCellSelectionEnabled(false);
这里我们禁止选中一个单元格 −
示例
package my;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
DefaultTableModel tableModel = new DefaultTableModel();
JTable table = new JTable(tableModel);
tableModel.addColumn("Language/ Technology");
tableModel.addColumn("Text Tutorial");
tableModel.addColumn("Video Tutorial");
tableModel.addColumn("Interview QA");
tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "Yes"});
tableModel.addRow(new Object[] { "F#", "Yes", "No", "Yes"});
tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "Yes"});
tableModel.addRow(new Object[] { "AWS", "No", "No", "Yes"});
tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "Yes"});
tableModel.addRow(new Object[] { "C#", "Yes", "Yes", "Yes"});
tableModel.addRow(new Object[] { "Java", "Yes", "No", "Yes"});
tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "Yes"});
tableModel.addRow(new Object[] { "MVC", "Yes", "No", "Yes"});
table.setCellSelectionEnabled(false);
JFrame f = new JFrame();
f.setSize(600, 400);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}
