Java Program to enable column selection in a JTable
To enable colum selection, use the setColumnSelectionAllowed() method and set it to TRUE −
table.setCell setColumnSelectionAllowed(true);
The following is an example to enable column selection in a table −
Example
package my; import java.awt.Color; import javax.swing.BorderFactory; import javax.swing.JFrame; import javax.swing.JPanel; import javax.swing.JScrollPane; import javax.swing.JTable; import javax.swing.border.TitledBorder; public class SwingDemo { public static void main(String[] args) { JFrame frame = new JFrame(); JPanel panel = new JPanel(); panel.setBorder(BorderFactory.createTitledBorder( BorderFactory.createEtchedBorder(), "ODI Rankings", TitledBorder.CENTER, TitledBorder.TOP)); String[][] rec = { { "1", "Steve", "AUS" }, { "2", "Virat", "IND" }, { "3", "Kane", "NZ" }, { "4", "David", "AUS" }, { "5", "Ben", "ENG" }, { "6", "Eion", "ENG" }, }; String[] header = { "Rank", "Player", "Country" }; JTable table = new JTable(rec, header); table.setShowHorizontalLines(true); table.setGridColor(Color.orange); table.setColumnSelectionAllowed(true); table.setRowSelectionAllowed(false); panel.add(new JScrollPane(table)); frame.add(panel); frame.setSize(550, 400); frame.setVisible(true); } }
The output is as follows. Here, we have selected a column. We can select a column now since setColumnSelectionAllowed() is set TRUE above −
Note − Do not forget to set table.setRowSelectionAllowed(false);
