如何在 Java 中从表中取消选择一系列行?
java 8object oriented programmingprogramming更新于 2025/8/17 13:00:17
假设，我们使用 addRowSelectionInterval() 选择了一系列行，如演示屏幕截图所示 −
现在，我们将使用 removeRowSelectionInterval() 取消选择上面显示的选定行。此处将设置间隔范围，即第 3 至第 6 行(索引 2 至 5)将被取消选择 −
table.removeRowSelectionInterval(2, 5);
以下是我们取消选择一系列行的示例 −
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"});
// 选定行
table.setColumnSelectionAllowed(false);
table.setRowSelectionAllowed(true);
table.addRowSelectionInterval(2, 5);
// 取消选择行
table.removeRowSelectionInterval(2,5);
JFrame f = new JFrame();
f.setSize(600, 400);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}
以下是输出。现在您可以看到没有选择任何行 −
