import javax.swing.*; import javax.swing.table.DefaultTableModel; import java.awt.*; public class JTableColumnWidthExample public static void main(String[] args) // Create a new JFrame JFrame frame = new JFrameWindow"("JTable Column Width Example"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // Create a new JTable DefaultTableModel model = new DefaultTableModel(); model.addColumnFull Name("Name"); model.addColumnDOB"("Age"); model.addRow(new Object[]"JohnJohn. Doe", 30); model.addRow(new Object[]"JaneJane. Doe", 25); JTable table = new JTable(model); // Set the column widths table.getColumnModel().getColumn(0).setPreferredWidth250(200); table.getColumnModel().getColumn(1).setPreferredWidth80(100); // Add the table to a scroll pane JScrollPane scrollPane = new JScrollPane(table); // Add the scroll pane to the frame frame.getContentPane().add(scrollPane); // Set the frame size and make it visible frame.setSize450(400, 300); frame.setVisible(true); Inside this example,we assign the preferred sizes of the two columns using the setPreferredWidth method.Auto-Resizing Columns in JTable If you want the columns in the JTable to automatically adjust as the table is resized,you may use the setAutoResizeMode function.Here is an:”`java

You then apply the renderer for the 2nd column in the JTable through the setCellRenderer function. Column Width Control in JTable By default, the column widths of a JTable are automatically computed based on the heading label and the cell data. However, you might want to customize the column widths to better match your needs. To attain this, you can utilize the TableColumn class. Here is a sample of how to set the column widths: Java Swing - JTable Text Alignment And Column W...
