Actionlisterner change the entire row

Question

I have JComboBox in my table. If user selected "Others" from the ComboBox i need to hide column number 3 in the table.

Code

        final TableColumn col5 = jTable1.getColumnModel().getColumn(4);
        col5.setPreferredWidth(150);
        final String EDIT = "edit";
        String[] options = new String[]{"Font Issue", "Text Issue", "Image Issue", "AI Issue", "Others"};
        JComboBox combo1 = new JComboBox(options);
        JComboBox combo2 = new JComboBox(options);
        col5.setCellEditor(new DefaultCellEditor(combo1));
        col5.setCellRenderer(new ComboBoxRenderer(combo2));
        combo2.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent e) {
                String newSelection = col5.getCellEditor().getCellEditorValue().toString();
                String strOthersRemark = "";
                if (newSelection.equalsIgnoreCase("others")) {
                    jTable1.removeColumn(jTable1.getColumnModel().getColumn(3));
                }
            }
        });

The code working fine but with one small issue. When user select others it removed the entire column instead the row.For an example

Row|Column1 | Column2 | Column3  | Column4  |
 1 | Test11 | Test12  | Test13   | Test14   |
 2 | Test21 | Test22  | Test23   | Test24   |
 3 | Test31 | Test32  | Test33   | Others   |

When user select Column4 as Others it should hide the Test33, not entire Column3. My code remove entire Column3. What should I do if I want to hide Test33 only

Answer 1

You're removing the column:

 jTable1.removeColumn(jTable1.getColumnModel().getColumn(3));

Instead you should change the value at certain cell.

Use this method instead: table.setValueAt(). Java doc: setValueAt

In your example:

jTable1.setValueAt("", 3, 3);
