英文:
PySimpleGUI Table index out of error when I skip first element of list
问题
在上面的代码中，你有一个名为 calendar_dates 的列表，你尝试将其作为参数传递给 PySimpleGUI 的 Table 元素，并使用 [1:] 来跳过第一个元素。但是你遇到了 Column index 1 out of bounds 的错误。
如果你想跳过第一个元素，你应该使用 [1:] 而不是 [:1]。所以你的代码是正确的，但你可能需要检查其他地方是否有可能引起这个错误的问题。
英文:
I'm making a small program with PySimpleGUI and encountered a very weird problem that doesn't make any sense to me.
def open_view_window(date):
calendar_dates = db_session.factory().query(Calendar.full_date).all()
calendar_dates = [ e[0] for e in calendar_dates ]
calendar_dates.sort(key=lambda date: datetime.strptime(date, "%d-%m-%Y"))
calendar_dates.insert(0, "")
print(calendar_dates)
tag_names = db_session.factory().query(Tag.name).all()
tag_names = [ e[0] for e in tag_names ]
tag_names.insert(0, "")
print(tag_names)
if date in calendar_dates:
default_val = date
else:
default_val = calendar_dates[1]
view_layout = [[sg.Text('Filter by:', key='FILTER')],
[sg.Text('Date:'), sg.Combo(values=calendar_dates, default_value=default_val, readonly=True), sg.Text('Tag:'), sg.Combo(values=tag_names, default_value=tag_names[0], readonly=True)],
[sg.Table(values=calendar_dates[1:])]]
As you can see in the code above, I have a list calendar_dates which I create from the contents of my database. After I sort the list, I insert a new empty element at the first position of the list.
But when I try to pass the list as an argument to the PySimpleGUI Table element and skip the first element with [1:], as it's no use for my case, I get the following error:
_tkinter.TclError: Column index 1 out of bounds
As I was trying to find out what I was doing wrong, I changed the list to skip the last element instead of the first with [:1], and that worked for some reason.
Please help, what am I doing wrong?

将您的表格元素设置标题，否则将出现异常
```python
_tkinter.TclError: 列索引 ? 超出界限
尝试删除与您问题无关的代码，在这里简化您的问题的代码。
import PySimpleGUI as sg
data = [['06/10/23'], ['06/11/23'], ['06/12/23'], ['06/13/23']]
calendar_dates = [date[0] for date in data]
data.insert(0, [""])
sg.set_options(font=("Courier New", 12))
layout = [
[sg.Text('按日期筛选:', key='FILTER')],
[sg.Text('日期:'), sg.Combo(values=calendar_dates)],
[sg.Table(values=data[1:], headings=["日期"], auto_size_columns=False, col_widths=[10], expand_x=True, justification='center')],
]
sg.Window('演示', layout).read(close=True)
英文:
Set the headings for your Table element, or you will get exception
