在excel xlsxwriter中追加行

Question

我创建了一个 xls 文件，我在其中将一些用户输入写入单元格。到目前为止一切顺利，该程序有效；它写了第一行。但是当我再次运行程序而不是将其写入第一个行之上的行时。我正在尝试了解如何使其将新行附加到 excel 表中保存并关闭它等

import xlsxwriter

workbook = xlsxwriter.Workbook("test.xlsx",)
worksheet = workbook.add_worksheet()

row = 0
col = 0

worksheet.write(row, col,     'odhgos')
worksheet.write(row, col + 1, 'e/p')
worksheet.write(row, col + 2, 'dromologio')
worksheet.write(row, col + 3, 'ora')


row += 1
worksheet.write_string(row, col,     odigosou)
worksheet.write_string(row, col + 1, dromou)
worksheet.write_string(row, col + 2, dromologio)
worksheet.write_string(row, col + 3, ora)

workbook.close()

使用我创建的这段代码，我可以在文件中写入内容，但是如何让它在现有工作表中追加一行。我看过的所有教程，我研究过的所有说明，都不起作用；我显然做错了什么，但我无法发现它。

Answer 1

如果文件不存在，则通过创建文件来避免 FileNotFound 错误的另一种解决方案：

from openpyxl import Workbook
from openpyxl import load_workbook

filename = "myfile.xlsx"
new_row = ['1', '2', '3']

# Confirm file exists. 
# If not, create it, add headers, then append new data
try:
    wb = load_workbook(filename)
    ws = wb.worksheets[0]  # select first worksheet
except FileNotFoundError:
    headers_row = ['Header 1', 'Header 2', 'Header 3']
    wb = Workbook()
    ws = wb.active
    ws.append(headers_row)

ws.append(new_row)
wb.save(filename)

# Note: if you're adding values from a list, you could instead use:
# new_row = ""
# new_row += [val for val in list]
# Similarly, for adding values from a dict:
# new_row = ""
# new_row = += [val for val in mydict['mykey'].values()]

Answer 2

问题：...如何在现有工作表中追加一行

使用openpyxl的解决方案，例如：

from openpyxl import load_workbook

new_row_data = [
    ['odhgos', 'e/p', 'dromologio', 'ora'],
    ['odigosou', 'dromou', 'dromologio', 'ora']]

wb = load_workbook("test/test.xlsx")
# Select First Worksheet
ws = wb.worksheets[0]

# Append 2 new Rows - Columns A - D
for row_data in new_row_data:
    # Append Row Values
    ws.append(row_data)

wb.save("test/test.xlsx")

使用 Python 测试：3.4.2 - openpyxl：2.4.1 - LibreOffice：4.3.3.2
