C# Select all columns in a row based on disctinct value

Hi, I have excel like this

and I want to select disctint on Column 2, and I want result return as below 

I used the following code, but it only return value on column 2 which is only country

string strConnection = "Provider=Microsoft.ACE.OLEDB.12.0;" +"Data Source = " + lblPath.Text.ToString() + "; Extended Properties = 'Excel 12.0;HDR=Yes;IMEX=1'";

            using (OleDbConnection excelConnection = new OleDbConnection(strConnection))
            {
                string strTable = Convert.ToString(comboBoxSelectTable.Text);

                string strSQL = "SELECT DISTINCT([Column 2]) FROM [Sheet1$]";

                using (OleDbCommand dbCommand = new OleDbCommand(strSQL, excelConnection))
                {
                    using (OleDbDataAdapter dataAdapter = new OleDbDataAdapter(dbCommand))
                    {
                        try
                        {
                            excelConnection.Open();

                            dataAdapter.Fill(dTable);

                            dataGridView1.DataSource = dTable;
                            
                        }
                        catch (Exception)
                        {
                            throw new Exception(ex.ToString());
                            
                        }
                        finally
                        {
                            dTable.Dispose();
                            dataAdapter.Dispose();
                            dbCommand.Dispose();

                        }
                    }
                }

Thank in advance,
