How to change column width of a table
- by vybhav
For the following code, I am not able to set the column size to a custom size. Why is it so?Also the first column is not being displayed.
import java.awt.BorderLayout;
import java.awt.GridLayout;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JTable;
import javax.swing.table.TableColumn;
public class Trial extends JFrame{
public void create(){
JPanel jp = new JPanel();
String[] string = {" ", "A"};
Object[][] data = {{"A", "0"},{"B", "3"},{"C","5"},{"D","-"}};
JTable table = new JTable(data, string);
jp.setLayout(new GridLayout(2,0));
jp.add(table);
table.setAutoResizeMode(JTable.AUTO_RESIZE_OFF);
TableColumn column = null;
for (int i = 0; i < 2; i++) {
column = table.getColumnModel().getColumn(i);
column.setPreferredWidth(20); //custom size
}
setLayout(new BorderLayout());
add(jp);
}
public static void main(String [] a){
Trial trial = new Trial();
trial.setSize(300,300);
trial.setVisible(true);
trial.setDefaultCloseOperation(Trial.EXIT_ON_CLOSE);
trial.create();
}
}
