如何在java中从另一个类中删除jTable列

import javax.swing.table.AbstractTableModel;

public class CustomTableModel extends AbstractTableModel {
    private Object[][] data;
    private String[] columnNames;

    public CustomTableModel(Object[][] data, String[] columnNames) {
        this.data = data;
        this.columnNames = columnNames;
    }

    @Override
    public int getColumnCount() {
        return columnNames.length;
    }

    @Override
    public int getRowCount() {
        return data.length;
    }

    @Override
    public Object getValueAt(int row, int col) {
        return data[row][col];
    }

    // 自定义的删除列的方法
    public void removeColumn(int col) {
        // 删除列的逻辑处理
    }
}

import javax.swing.JFrame;
import javax.swing.JTable;
import javax.swing.JScrollPane;

public class MainClass {
    public static void main(String[] args) {
        Object[][] data = {{"1", "John", "Doe"}, {"2", "Jane", "Smith"}};
        String[] columnNames = {"ID", "First Name", "Last Name"};

        CustomTableModel model = new CustomTableModel(data, columnNames);
        JTable table = new JTable(model);

        JFrame frame = new JFrame();
        frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        frame.add(new JScrollPane(table));
        frame.pack();
        frame.setVisible(true);
    }
}

public void removeColumn(int col) {
    Object[][] newData = new Object[data.length][data[0].length - 1];
    String[] newColumnNames = new String[columnNames.length - 1];

    int dataIndex = 0;
    int columnIndex = 0;
    for (int i = 0; i < data.length; i++) {
        for (int j = 0; j < data[i].length; j++) {
            if (j != col) {
                newData[dataIndex][columnIndex] = data[i][j];
                columnIndex++;
            }
        }
        dataIndex++;
        columnIndex = 0;
    }

    int columnNameIndex = 0;
    for (int i = 0; i < columnNames.length; i++) {
        if (i != col) {
            newColumnNames[columnNameIndex] = columnNames[i];
            columnNameIndex++;
        }
    }

    data = newData;
    columnNames = newColumnNames;

    fireTableStructureChanged();
}
