How insert or delete row of JPanel consisting of 3 elements - swing

Question

I am using JPanel of three elements row: JLabel, JTextField, JButton.
jPanel.setLayout(new GridLayout(0,3));
I need button of a row to delete its row from JPanel.
for(Pair<JLabel, JTextField> pair: labelTextFieldPairs) {
jPanel.add(pair.getFirst());
jPanel.add(pair.getSecond());
jPanel.add(createDeleteButton());//how to implement that method?
}
Also I have a button to add row to JPanel.
How to do that? Or is it better to use JTable for that?
What if I need to insert row consisting of 3 elements somewhere in the middle of JPanel. How to do that?
JButton addNumberToListButton = new JButton("add number to list");
addNumberToListButton.addActionListener(new ActionListener() {
#Override
public void actionPerformed(ActionEvent e) {
Pair<JLabel, JTextField> pair = new Pair<>(new JLabel(), new JTextField());
labelTextFieldPairs.add(pair);
jPanel.add(pair.getFirst(), labelTextFieldPairs.size());
jPanel.add(pair.getSecond(), labelTextFieldPairs.size());
jPanel.add(createDeleteButton(), labelTextFieldPairs.size());
//will this 3 lines work?
}
});

Answer 1

Deletion operation looks like this:
public void removeRow(int firstComponentInRow) {
labelTextFieldPairs.remove(firstComponentInRow / numberOfColumns);
jPanel.remove(firstComponentInRow);
jPanel.remove(firstComponentInRow);
jPanel.remove(firstComponentInRow);
jPanel.revalidate();
jPanel.repaint();
}
and add operation looks like this:
public void addRow(Pair<JLabel, JFormattedTextField> labelAndTextField) {
labelTextFieldPairs.add(labelAndTextField);
jPanel.add(labelAndTextField.getFirst(), (labelTextFieldPairs.size() - 1) * numberOfColumns);
jPanel.add(labelAndTextField.getSecond(), (labelTextFieldPairs.size() - 1) * numberOfColumns + 1);
jPanel.add(createDeleteButton((labelTextFieldPairs.size() - 1) * numberOfColumns), (labelTextFieldPairs.size() - 1) * numberOfColumns + 2);
jPanel.revalidate();
jPanel.repaint();
}
where labelTextFieldPairs.size() used as insertion index.
