`get_values` does not return all data in some scenarios with empty data

Hello! Thanks for your time. I wanted to report a potential bug in the get_values function. When you have a spreadsheet that has say 6 columns with headers, where data should be and you make a query for a particular row, there is a certain scenario where empty data fields are not returned. This can be confusing for downstream users of the gspread API who want to say, convert the row into a dictionary (ala get_all_records).

This scenario occurs when data is laid out like this:

header1, header2, header3, header4, header5, header6
x1, , , x4, ,

In that data above header5 and header6 are empty for the first row. Suppose you made this call:

ws.get_values("A1:1")

You only get back:

[['x1',,,'x4']]

As opposed to what I would expect:

[['x1',,,'x4',,]]

Minimal reproducer:

(Pdb++) ws.get_values("A7:7")
[['', 'kl3020', '', '07/26/2021']]

Expected result:

(Pdb++) ws.get_values("A7:7")
[['', 'kl3020', '', '07/26/2021', '', '']]

You’re right, issue re-open. If you have a PR ready feel free to open it I’ll review it.

Thanks.

This is sample worksheet with name ‘test’

	A	B	C	D	E	F
1	ID	NAME	math	science	python	rock
2	9938	aaaa	_	_	90	_
3	9738	bbbb	30	_	55	45
4	4821	cccc	_	40	_	_
5	3908	dddd	_	_	100	_
6	7182	eeee	_	90	_	80

* in this example, _(underbar) means empty cell

* ROWs : 1 … 6 // COLs : A … F

... # auth stuffs

ws = spreadSheet.worksheet('test')

case 1. when requesting values A1:E3 (expectable)

result = ws.get_values('A1:E3')
# result
[
    ['ID', 'NAME', 'math', 'science', 'python'],
    [9938, 'aaaa', '', '', 90 ],
    [9738, 'bbbb', 30, '', 55]
]

case 2. when requesting values C1:E3 (expectable)

result = ws.get_values('C1:E3')
# result
[
    ['math', 'science', 'python'],
    ['', '', 90 ],
    [30, '', 55]
]

case 3. when requesting values A1:F2 (expectable)

result = ws.get_values('A1:F2')
# result
[
    ['ID', 'NAME', 'math', 'science', 'python', 'rock'],
    [9938, 'aaaa', '', '', 90, '' ],
]

edit added : use case for pandas.DataFrame

result = ws.get_values('A1:F2')
df2 = pands.DataFrame(result)

print(df2)
#    ID    NAME      math    science   python   rock
# 0  9938  aaaa                        90

case 4. when requesting values A2:F2 (quite not expectable)

result = ws.get_values('A2:F2')
# result
[
    [9938, 'aaaa', '', '', 90],
]

what some people would have expected :

[
    [9938, 'aaaa', '', '', 90, '']
]

---

comparing with case 2 and case 4,

we could know google search from left to right

but don’t take into account when cell is empty

just like they are using str.rstrip() python string method

tl;dr google spread request return results after using rstrip()-like method

any thing to fix?
