We then set this renderer for the second column of the JTable using the setCellRenderer method.

Here is an example of how to change the text alignment for a specific column: Java Swing - JTable Text Alignment And Column W...

Here is an example:

By default, the text alignment of a JTable is left-aligned for all columns. However, you may want to change the text alignment for specific columns or for the entire table. To achieve this, you can use the TableCellRenderer interface. import javax

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 JFrame("JTable Column Width Example"); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); // Create a new JTable DefaultTableModel model = new DefaultTableModel(); model.addColumn("Name"); model.addColumn("Age"); model.addRow(new Object[]{"John Doe", 30}); model.addRow(new Object[]{"Jane Doe", 25}); JTable table = new JTable(model); // Set the column widths table.getColumnModel().getColumn(0).setPreferredWidth(200); table.getColumnModel().getColumn(1).setPreferredWidth(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.setSize(400, 300); frame.setVisible(true); } } In this example, we set the preferred widths of the two columns using the setPreferredWidth method.

Here is an example of how to set the column widths: ; import javax

If you want the columns of a JTable to automatically resize when the table is resized, you can use the setAutoResizeMode method.
