How to highlight a row in a table with Java Swing?
To highlight a row in a table, you can use the addRowSelectionInterval() method. At first create a table −
DefaultTableModel tableModel = new DefaultTableModel(); JTable table = new JTable(tableModel);
Add some columns −
tableModel.addColumn("Language/ Technology");
tableModel.addColumn("Text Tutorial");
tableModel.addColumn("Video Tutorial");
tableModel.addColumn("Views");Now, add rows to the table −
tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "2350"});
tableModel.addRow(new Object[] { "MVC", "Yes", "No", "1500"});
tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "3400"});
tableModel.addRow(new Object[] { "F#", "Yes", "No", "7890"});
tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "10600"});
tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "4900"});Highlight a single row by adding interval of rows. Set the same index for both the parameters since we want only a single row to be highlighted −
table.addRowSelectionInterval(4, 4);
The following is an example to highlight a row in JTable −
Example
package my;
import java.awt.Color;
import java.awt.Font;
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("Views");
tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "2350"});
tableModel.addRow(new Object[] { "MVC", "Yes", "No", "1500"});
tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "3400"});
tableModel.addRow(new Object[] { "F#", "Yes", "No", "7890"});
tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "10600"});
tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "4900"});
tableModel.addRow(new Object[] { "AWS", "No", "Yes", "8900"});
tableModel.addRow(new Object[] { "C#", "Yes", "Yes", "1300"});
tableModel.addRow(new Object[] { "Java", "Yes", "No", "9686"});
tableModel.addRow(new Object[] { "jQuery", "Yes", "Yes", "4500"});
tableModel.addRow(new Object[] { "Python", "Yes", "No", "6789"});
tableModel.addRow(new Object[] { "Scala", "Yes", "No", "3400"});
tableModel.addRow(new Object[] { "Swift", "No", "Yes", "9676"});
table.addRowSelectionInterval(4, 4);
table.setBackground(Color.white);
table.setForeground(Color.BLUE);
Font font = new Font("Verdana", Font.CENTER_BASELINE, 12);
table.setFont(font);
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
frame.setVisible(true);
}
}Output
