Disallow resizing a column by dragging between headers in a JTable Component with Java
Let us first create a table with rows and columns −
String data[][] = { {"Australia","5","1"}, {"US","10","2"}, {"Canada","9","3"}, {"India","7","4"}, {"Poland","2","5"}, {"SriLanka","5","6"} }; String col [] = {"Team","Selected Players","Rank"}; DefaultTableModel tableModel = new DefaultTableModel(data,col); JTable table = new JTable(tableModel);
Now, we will disable resizing of columns by dragging headers −
table.getTableHeader().setResizingAllowed(false);
The following is an example to disallow resizing a column by dragging between headers in a JTable: −
Example
package my; import java.awt.Dimension; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JRootPane; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.table.DefaultTableModel; public class SwingDemo { public static void main(String[] argv) throws Exception { JFrame frame = new JFrame("Demo"); JPanel panel = new JPanel(); String data[][] = { {"Australia","5","1"}, {"US","10","2"}, {"Canada","9","3"}, {"India","7","4"}, {"Poland","2","5"}, {"SriLanka","5","6"} }; String col [] = {"Team","Selected Players","Rank"}; DefaultTableModel tableModel = new DefaultTableModel(data,col); JTable table = new JTable(tableModel); table.getTableHeader().setResizingAllowed(false); Dimension dim = new Dimension(50,2); table.setIntercellSpacing(new Dimension(dim)); JScrollPane scrollPane = new JScrollPane(table); panel.add(scrollPane); frame.add(panel); frame.setSize(600,400); frame.setUndecorated(true); frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); frame.getRootPane().setWindowDecorationStyle(JRootPane.COLOR_CHOOSER_DIALOG); frame.setVisible(true); } }
The output is as follows. You won’t be able to resize the columns by dragging between table header −
