要在 Java Swing 中选择表格中的所有单元格，您需要使用 selectAll() 方法。假设以下是表格的行数和列数减去
String[][] rec = {
{ "001","Shirts","40"," },
{ "002","Trousers","250"," },
{ "003","Jeans","25"," },
{ "004","Applicances","90"," },
{ "005","Mobile Phones","200"," },
{ "006","Hard Disk","150"," },
};
String[] header = { "ID","Product","Quantity"," };
设置为表格 −
JTable table = new JTable(rec, header);
现在选择所有行和列 −
table.selectAll();
以下是选择表格中所有单元格的示例 −
示例
package my;
import java.awt.Color;
import javax.swing.BorderFactory;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.border.TitledBorder;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame();
JPanel panel = new JPanel();
panel.setBorder(BorderFactory.createTitledBorder(
BorderFactory.createEtchedBorder(), "Stock", TitledBorder.CENTER, TitledBorder.TOP));
String[][] rec = {
{ "001", "Shirts", "40" },
{ "002", "Trousers", "250" },
{ "003", "Jeans", "25" },
{ "004", "Applicances", "90" },
{ "005", "Mobile Phones", "200" },
{ "006", "Hard Disk", "150" },
};
String[] header = { "ID", "Product", "Quantity" };
JTable table = new JTable(rec, header);
table.setShowHorizontalLines(true);
table.setGridColor(Color.blue);
table.selectAll();
panel.add(new JScrollPane(table));
frame.add(panel);
frame.setSize(550, 400);
frame.setVisible(true);
}
}
这将产生以下输出 −
