How to show more than one table in single Data Grid Control

Good Day! I showed single remote database table  in Data Grid View Control. But i don't know how to show more than one table in single Data grid view control. I am using more than one tab page. every tab pages are contains different field names. I want to show different tab page remote database table into a single data grid view control.

code is:

dataGridView1.AutoGenerateColumns = false;
               dataGridView1.ColumnCount = 20;

SqlConnection cn = null;
            string connectString = "";
            SqlCommand cmd = null;
            SqlDataReader rdr = default(SqlDataReader);

            connectString = string.Format("Data Source = 192.168.1.105,1433;Initial Catalog=itcdb;Persist Security Info=True;User ID=wince;Password=wince1;");
            cn = new SqlConnection(connectString);

            try
            {
                if (cn.State == ConnectionState.Closed)
                {
                    cn.Open();
                }
            }
            catch (Exception ex)
            {
                MessageBox.Show("Open Error");
                MessageBox.Show(ex.Message);
            }



            try
            {

                cmd = new SqlCommand("select * from tAerator1", cn);
                cmd.CommandType = CommandType.Text;
                SqlDataAdapter sdr = new SqlDataAdapter(cmd);
                DataTable dt = new DataTable();
                sdr.Fill(dt);
                rdr = cmd.ExecuteReader();

                while (rdr.Read())
