I have an element E that is 1000px wide, that is within a parent container P.
Of E's 1000 pixels of width, the columns x position 600–800px are more important than the others, so as its parent element gets narrower, I'd like to position E within P so that these pixels are visible and centred within P (until this is no longer possible).
So, if P can fit the entire width of E, no problem! Just centre E within P:
┌──────────────────────────────────────────────────────────────┐

However, if the parent is resized to be e.g. 250px wide, E should be centred around x=700px:

Is this possible to achive with CSS? (Maybe using calc()?)
Bonus: Is it possible to have the overflow be scrollable? (If so, I guess JS is needed?)
You could do this with absolute positioning. For larger screens, position the #Important div absolutely 200px from the right-end of E. For smaller screens, position the div absolutely from the left (e.g., 50px from the left).
See this CodePen for the solution.
With this method, the contents of #Important div will overlap the contents of E which I'm assuming is what you want based on the visuals in your question.

I need to add new column first_payment
first_payment takes value 1 if action is payment && it is first payment for a user. Otherwise it takes value 0.
the first_payment should be checked for all period

I couldn't find much about ClickHouse, but it doesn't appear to support Windowed Functions.
Your example output also seems to be exactly the same as your sample table, plus one additional column, so I'm not sure what you GROUP BY was meant to achieve.
So, I'd use a LEFT JOIN on to a sub-query.
SELECT
payments_all.*,
CASE WHEN user_summary.user_id IS NOT NULL THEN 1 ELSE 0 END AS first_payment
FROM
payments_all
LEFT JOIN
(
SELECT
user_id,
factory,
MIN(created_at) AS first_created_at
FROM
payments_all
WHERE
action = 'payment'
GROUP BY
user_id,
factory
)
AS user_summary
ON payments_all.user_id = user_summary.user_id
ON payments_all.factory = user_summary.factory
AND payments_all.created_at = user_summary.first_created_at
WHERE
(payments_all.factory IN ('0_factory', '1_factory', '2_factory'))
AND (payments_all.created_at >= toDate('2019-01-01 00:00:00'))
AND (payments_all.created_at < toDate('2021-10-01 00:00:00'))
As I can see for first payment the payment_id is always 1. So, I think you can use CASE WHEN payment_id=1 Then 1 ELSE 0 END AS first_payment. Please check query below =>
WITH CTE AS
(SELECT
factory,
user_id,
payment_id,
action,
created_at
FROM payments_all
WHERE (payments_all.action = 'payment') AND (payments_all.factory IN ('0_factory', '1_factory', '2_factory')) AND isNotNull(payments_all.created_at)
GROUP BY
factory,
user_id,
payment_id,
action
HAVING (min(created_at) >= toDate('2019-01-01 00:00:00')) AND (min(created_at) < toDate('2021-10-01 00:00:00'))
) T1
SELECT *,CASE WHEN payment_id=1 Then 1
ELSE 0 END AS first_payment
FROM CTE
ORDER BY T1.user_id
NOTE: Query is written in SQL Server. Please check and let me know.

You are probably on Julia 1.0. Try switching to Julia 1.3.1 (current release) and the problem should disappear.
If you have to stick to Julia 1.0 the problem is that nothing value is not allowed to be printed in this version (it is allowed now in Julia 1.3.1 so that is why switching solves your problem). In order to solve it the simplest thing is to replace nothing with missing (as probably if you have nothing in your data then missing is not used in it so it should be safe to use it as a replacement).
The code that will work in this case is:
filename = "Alldata.csv"
CSV.write(filename, something.(bf, missing))
After this operation in the saved file each occurrence of nothing in your original data frame will be stored as an empty field in a specific row (and when you read back the file using CSV.read it will take a missing value in the resulting data frame).
I am trying to make a survey site, but I have not been able to normalize the database. I do not know how to correlate questions and answers in the database. There is a very strong relationship between questionnaire and questionnaire. Because I have the QuestionID in the question table as the primary Key, the ID numbers of the question numbers are unique. This is how the answer table works. How am I supposed to do that?
