使用 openpyxl 获取Excel总列数，总行数，获取一行所有值，获取一列所有值。

    def get_row_clo_num(self):
        rows = self.ws.max_row
        columns = self.ws.max_column
        return rows, columns

    # 获取某个单元格的值
    def get_cell_value(self, row, column):
        cell_value = self.ws.cell(row=row, column=column).value
        return cell_value

    # 获取某列的所有值
    def get_col_value(self, column):

            column_data.append(cell_value)
