How can I get a table below using DataView?

[HP2005]

I want get a tabel like below:
time progress question
2025-02-01 jingdu a1 wenti a1
2025-02-03 jingdu a2 wenti a2

note 2025-02-01 :

Customer

[[Customer A]]

• progress::jindu a1
• question::wenti a1

[[Customer B]]

• progress::jingdu b1
• question::wenti b2

note 2025-02-03:

Customer

[[Customer A]]

• progress::jindu a2
• question::wenti a2

[[Customer B]]

• progress::jindu b2
• question::wenti b2

Customer B and Customer A are independent md files.

my query is

TABLE WITHOUT ID "<nobr>" + file.link + "</nobr>" AS 日期,progress
FROM [[Customer A]] 
FLATTEN list(filter(file.lists, (x) => meta(x.section).subpath="Customer A").text) as progress

How can I get two columns ( progess and question )?

The following is untested and written in the middle of the night:

```dataview
TABLE WITHOUT ID 
  "<nobr>" + origin[2] + "</nobr>" AS 日期, 
  nonnull(rows.itemProgress)[0] as progress,
  nonnull(rows.itemQuestion)[0] as question
FROM [[Customer A]] 
FLATTEN file.lists as item
FLATTEN item.progress as itemProgress
FLATTEN item.question as itemQuestion
FLATTEN meta(item.section).subpath as itemHeader
WHERE string(itemHeader) = "Customer A"
GROUP BY [file.name, itemHeader, file.link] as origin
```

The idea is to make groups based on each section in a file (allowing just one question per customer per daily note), and then use a little trickery to pull out the fields from the resulting rows lists.

Hopefully I’ve not made too many small typos, but the logic should be sound. A little worried whether the header being a link is causing any issues. If I get around to it I’ll test it during the day (at least 5-6 hours from now).

It works,too amazing.
I’m new to Obsidian, I originally thought that JavaScript was needed to solve this problem.
You’re so professional. Thank you very much. I need to study your code carefully. Later, I’ll add tags to classify the customer diaries, and then output the customer information of specific types.
