Java Program to add Combo Box to JTable
Use the JComboBox to add a combo box to a table -
JComboBox<String> comboBox = new JComboBox<>();
Now, add the combo box items -
comboBox.addItem("Asia");
comboBox.addItem("Europe");
comboBox.addItem("North America");
comboBox.addItem("South America");Now, use the TableColumn and set the column wherein you want to set the above ComboBox items -
TableColumn testColumn = table.getColumnModel().getColumn(0);
Set the editor with the combo box -
testColumn.setCellEditor(new DefaultCellEditor(comboBox));
The following is an example to add JComboBox to JTable:
package my;
import java.awt.Color;
import java.awt.Font;
import javax.swing.DefaultCellEditor;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.JTableHeader;
import javax.swing.table.TableColumn;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
JTable table = new JTable(5, 5);
Font font = new Font("Verdana", Font.PLAIN, 12);
table.setFont(font);
table.setRowHeight(30);
table.setBackground(Color.orange);
table.setForeground(Color.white);
TableColumn testColumn = table.getColumnModel().getColumn(0);
JComboBox<String> comboBox = new JComboBox<>();
comboBox.addItem("Asia");
comboBox.addItem("Europe");
comboBox.addItem("North America");
comboBox.addItem("South America");
comboBox.addItem("Africa");
comboBox.addItem("Antartica");
comboBox.addItem("Australia");
testColumn.setCellEditor(new DefaultCellEditor(comboBox));
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
