How to create JTable from two dimensional array in Java?
With two dimensional array, set the columns of a table. Additionally, we have set the rows using a one-dimensional array as shown below −
DefaultTableModel tableModel = new DefaultTableModel(new Object[][] {
{ "Mobile Phones", "100" }, { "RAM", "200" }, { "Caps", "50" },
{ "Tablet", "80" }, { "LED", "400" }, { "Trousers", "350" },
{ "T-Shirt", "500" }, { "Hoodie", "650" }, { "Jeans", "900" } },
new Object[] { "Items", "Quantity" }
);Now set the table model to the table −
JTable table = new JTable(tableModel);
The following is an example to create a table from two dimensional array −
Example
package my;
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(new Object[][] {
{ "Mobile Phones", "100" }, { "RAM", "200" }, { "Caps", "50" },
{ "Tablet", "80" }, { "LED", "400" }, { "Trousers", "350" },
{ "T-Shirt", "500" }, { "Hoodie", "650" }, { "Jeans", "900" } },
new Object[] { "Items", "Quantity" }
);
JTable table = new JTable(tableModel);
Font font = new Font("Verdana", Font.PLAIN, 12);
table.setFont(font);
table.setRowHeight(30);
JFrame frame = new JFrame();
frame.setSize(600, 400);
frame.add(new JScrollPane(table));
frame.setVisible(true);
}
}This will produce the following output −
