获取 combined/merged 个单元格值

Question

我正在编写一个新的 python 脚本，需要从 google 工作表中提取数据，但是有很多单元格是 merged/combined，而且只有左上角的单元格从此合并中具有价值。在所有合并的单元格上都具有该值很重要。

我该怎么做？

Python 3.8.5 + gspread 3.6.0

注意：每条评论“trying to get...”，其正下方的代码应return与前面代码相同的值。

电子表格测试： https://docs.google.com/spreadsheets/d/17Dyxufu1y1ouBCPkf5Y7Vt1UW70WroK0Moy_DD7bZKc/edit?usp=sharing

重现问题的代码：

import gspread
from oauth2client.service_account import ServiceAccountCredentials
import os
import pprint

here = os.path.dirname(os.path.abspath(__file__))
secret = os.path.join(here, 'credentials.json')

scope = ['https://spreadsheets.google.com/feeds']
creds = ServiceAccountCredentials.from_json_keyfile_name(secret, scope)

client = gspread.authorize(creds)

sheet = client.open_by_key('17Dyxufu1y1ouBCPkf5Y7Vt1UW70WroK0Moy_DD7bZKc')
ws = sheet.sheet1
pp = pprint.PrettyPrinter()

#getting the FIRST text
result = ws.acell('A1')
pp.pprint('A1: '+result.value)

#trying to get the SAME text on the cell col+1
result = ws.acell('A2')
pp.pprint('A2: '+result.value)

#getting the 'simple_cell'
result = ws.acell('C2')
pp.pprint('C2: '+result.value)

#getting the 'row_merged'
result = ws.acell('D2')
pp.pprint('D2: '+result.value)

#trying to get 'row_merged' on row+1
result = ws.acell('E2')
pp.pprint('E2: '+result.value)

#getting the 'col_merged'
result = ws.acell('D6')
pp.pprint('D6: '+result.value)

#trying to get 'col_merged' on col+1
result = ws.acell('D7')
pp.pprint('D7: '+result.value)

输出是这样的：

('A1: just to confirm, the value "row_merged" has been put to cell D2 originally. Value "col_merged" is in D6 initially. Since it's merged, the expected result should be found on all merged cells')
'A2: '
'C2: simple cell'
'D2: row_merged'
'E2: '
'D6: col_merged'
'D7: '

关键是：A2 必须等于 A1...E2=D2，D7==D6...但似乎没有办法用 gspread 处理合并的单元格。

Answer 1

我相信你的目标如下。

• 您想使用 python 的 gspread 从合并的单元格中检索值。

例如，在您的示例电子表格中，合并了单元格“A1:L12”。在这种情况下，当使用 Sheets API 从“A1:L12”的合并单元格中检索值时，just to confirm, the value "row_merged" has been put to cell D2 originally. Value "col_merged" is in D6 initially. Since it's merged, the expected result should be found on all merged cells 仅检索单元格“A1”。因此，为了从“A1:L12”的所有单元格中检索相同的值，需要将值放入单元格“A2:L12”。不幸的是，在Sheets API中似乎没有直接实现这种情况的方法。因此，在这个答案中，我想使用脚本来提出这个建议。

顺便说一句，关于 result = ws.acell('A2') 在你的脚本中，这个单元格没有合并，它是空的。所以在这种情况下，我认为空值是正确的。我认为您可能想要检查单元格“B1”。在这个答案中，也考虑到了这一点。

示例脚本：

spreadsheet_id = '###'  # Please set the Spreadsheet ID.
sheet_name = 'Sheet1'  # Please set the sheet name.

client = gspread.authorize(credentials)
access_token = client.auth.token
url = "https://sheets.googleapis.com/v4/spreadsheets/" + \
    spreadsheet_id + "?fields=sheets&ranges=" + sheet_name
res = requests.get(url, headers={"Authorization": "Bearer " + access_token})
obj = res.json()
# print(obj['sheets'][0]['merges'])

sheet = client.open_by_key(spreadsheet_id)
ws = sheet.worksheet(sheet_name)

# 1. All values are retrieved.
values = ws.get_all_values()

# 2. Put the values to the merged cells.
if 'merges' in obj['sheets'][0].keys():
    for e in obj['sheets'][0]['merges']:
        value = values[e['startRowIndex']][e['startColumnIndex']]
        rows = len(values)
        if rows < e['endRowIndex']:
            for i in range(0, e['endRowIndex'] - rows):
                values.append([''])
        for r in range(e['startRowIndex'], e['endRowIndex']):
            cols = len(values[r])
            if cols < e['endColumnIndex']:
                values[r].extend([''] * (e['endColumnIndex'] - cols))
            for c in range(e['startColumnIndex'], e['endColumnIndex']):
                values[r][c] = value

# For A1
print('A1: '+values[0][0])

# For B1
# output: just to confirm, the value "row_merged" has been put to cell D2 originally. Value "col_merged" is in D6 initially. Since it's merged, the expected result should be found on all merged cells
print('B1: '+values[0][1])

# For C2
# output: simple cell
print('C2: '+values[1][2])

# For D2
# output: row_merged
print('D2: '+values[1][3])

# For E2
# output: row_merged
print('E2: '+values[1][4])

# For D6
# output: col_merged
print('D6: '+values[5][3])

# For D7
# output: col_merged
print('D7: '+values[6][3])

注：

• 在此示例脚本中，Sheets API 中的“spreadsheets.get”方法与 requests 一起使用，使用从 gspread 的 client = gspread.authorize(credentials) 检索到的访问令牌。
• 在此示例脚本中，值在列表中进行处理。因此，当您从合并的单元格中检索值时，请从列表 values.
中检索它们
