我正在尝试在第二行中为comboBox添加其他项

Question

我需要为相同的“ ComboBox Text Header” comboBox 1“ Stations”和comboBox2“ Citiyes”添加不同的项目， 第二行[第2行]。 以及三个[Row = 3]的不同项目，依此类推。.[Row = 8]。

        private void Form1_Load(object sender, EventArgs e)
        {
            DataTable dt = new DataTable();


                            dt.Columns.Add("ID");
                            dt.Columns.Add("Branches");
                            dt.Rows.Add("1", "Khartuom");
                            dataGridView1.DataSource = dt;



            DataGridViewComboBoxColumn combo = new DataGridViewComboBoxColumn();


            combo.HeaderText = "Stations";

            combo.Items.Add("Al mena");
            combo.Items.Add("Bahir New Station");
            combo.Items.Add("Libia");
            combo.Items.Add("PUblic shog");



            dataGridView1.Columns.Add(combo);

            DataGridViewComboBoxColumn combo2 = new DataGridViewComboBoxColumn();
            combo2.HeaderText = "Citiyes";

            combo2.Items.Add("Port Sudan");
            combo2.Items.Add("Kasala");
            combo2.Items.Add("Madani");
            combo2.Items.Add("AlNohod");

            dataGridView1.Columns.Add(combo2);


            DataGridViewLinkColumn link = new DataGridViewLinkColumn();

            link.HeaderText = "Links page";
            dataGridView1.Columns.Add(link);


            DataGridViewImageColumn Image = new DataGridViewImageColumn();
            Image.HeaderText = "Delete";
            dataGridView1.Columns.Add(Image);


            DataGridViewImageColumn Image2 = new DataGridViewImageColumn();
            Image2.HeaderText = "Edit";
            dataGridView1.Columns.Add(Image2); 
}
    }
}
