Java Program to deselect a range of columns in a JTable
At first, let’s say, we have selected a range of columns using addColumnSelectionInterval() as shown in the demo screenshot −
Now, we will deselect the above shown selected columns using removeColumnSelectionInterval(). The range is to be set here for interval i.e column 1 to 2 will get deselected −
table.removeColumnSelectionInterval(1, 2);
The following is our example to deselect a range of columns −
Example
package my;
import javax.swing.JFrame;
import javax.swing.JScrollPane;
import javax.swing.JTable;
import javax.swing.table.DefaultTableModel;
public class SwingDemo {
public static void main(String[] argv) throws Exception {
DefaultTableModel tableModel = new DefaultTableModel();
JTable table = new JTable(tableModel);
tableModel.addColumn("Language/ Technology");
tableModel.addColumn("Text Tutorial");
tableModel.addColumn("Video Tutorial");
tableModel.addColumn("Interview QA");
tableModel.addRow(new Object[] { "ASP.NET", "Yes", "Yes", "Yes"});
tableModel.addRow(new Object[] { "F#", "Yes", "No", "Yes"});
tableModel.addRow(new Object[] { "SharePoint", "Yes", "Yes", "Yes"});
tableModel.addRow(new Object[] { "AWS", "No", "No", "Yes"});
tableModel.addRow(new Object[] { "Blockchain", "Yes", "No", "Yes"});
tableModel.addRow(new Object[] { "C#", "Yes", "Yes", "Yes"});
tableModel.addRow(new Object[] { "Java", "Yes", "No", "Yes"});
tableModel.addRow(new Object[] { "NodeJS", "No", "Yes", "Yes"});
tableModel.addRow(new Object[] { "MVC", "Yes", "No", "Yes"});
table.setColumnSelectionAllowed(true);
table.addColumnSelectionInterval(1, 2);
table.setRowSelectionAllowed(false);
table.removeColumnSelectionInterval(1, 2);
JFrame f = new JFrame();
f.setSize(600, 400);
f.add(new JScrollPane(table));
f.setVisible(true);
}
}Following is the output. Now you can see none of the column is selected −
