如何使用 Java 在表格中显示垂直网格线?
java 8object oriented programmingprogramming
要在表格中显示垂直网格线，请使用 setShowVerticalLines() 方法。让我们首先创建一个表格 −
String[][] rec = {
{ "1", "Steve", "AUS" },
{ "2", "Virat", "IND" },
{ "3", "Kane", "NZ" },
{ "4", "David", "AUS" },
{ &";5", &";Ben", &";ENG" },
{ &";6", &";Eion", &";ENG" },
};
String[] header = { &";Rank", &";Player", &";Country" };
JTable table = new JTable(rec, header);
现在，让我们显示垂直网格线 −
table.setShowVerticalLines(true);
您还可以为这些线指定颜色 −
table.setGridColor(Color.blue);
以下是在 JTable 中显示垂直网格线的示例 −
示例
package my;
import java.awt.Color;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTable;
public class SwingDemo {
public static void main(String[] args) {
JFrame frame = new JFrame();
JPanel panel = new JPanel();
String[][] rec = {
{ "1", "Steve", "AUS" },
{ "2", "Virat", "IND" },
{ "3", "Kane", "NZ" },
{ "4", "David", "AUS" },
{ "5", "Ben", "ENG" },
{ "6", "Eion", "ENG" },
};
String[] header = { "Rank", "Player", "Country" };
JTable table = new JTable(rec, header);
table.setShowGrid(false);
table.setShowVerticalLines(true);
table.setGridColor(Color.blue);
panel.add(new JScrollPane(table));
frame.add(panel);
frame.setSize(550, 400);
frame.setVisible(true);
}
}
输出
