Answered 2022-Jan-04 at 17:21First off, consider posting this over at https://codereview.stackexchange.com/ to get an extensive review of your code, because there is a lot that could be done better. Two suggestions for now:
Avoid hard coding HTML inside your JS (this question is a first good step)
There is normally no need to give everything a unique ID. Instead you usually can reference everything in relation to each other, possibly with help of classes. For example, the edit/save/delete buttons can look up which table row their in to find the elements they needs.
In this specific case you could clone the existing select from the HTML:

Im fetching data from an API and changing the value from the frontend to display it in a table. Im fetching a list of objects and storing it in a state and displaying the objects in the state in a html table. The table has a checkbox to display a boolean value. If the value is true, then defaultChecked is true in the checkbox. There's a checkbox in the table header to check or uncheck all items.
The following is the json object which i fetch.
...ANSWER
Answered 2021-Dec-23 at 09:16I don't see any overt issues in this code, but it is quite verbose. Both logic branches are identical save for the completed
boolean value assigned. When updating arrays in React it is common to use functional state updates to make the shallow copy of the previous state, not whatever state may be closed over in the callback scope.

QUESTION
I am using Google Sheets API to retrieve data from online spreadsheets and to read them into a pandas dataframe. I have successfully set up the script to fetch the data but this default implementation fetches everything, even hidden rows/columns. There are many rows on the spreadsheet that have been hidden. I do not want to retrieve those, as the hidden state of a row means it is irrelevant. Therefore, I am looking for an approach to fetch a spreadsheet without the manually hidden rows/columns. Or, alternatively, an approach to fetch a spreadsheet content and exclude the hidden cells afterwards. So far I haven't managed to figure out whether such a feature is implemented in the Google Sheets API.
My current, working implementation is as follows. The problem here is that this includes even hidden rows/columns:
...ANSWER
Answered 2021-Nov-04 at 00:54About your following goal,
This problem, in my opinion, is different from merely filtering the spreadsheet based on a column value, as described here. I want to fetch only those rows of a spreadsheet that are not hidden. The default API call to fetch content of a spreadsheet (see my code above) fetches all the rows, even those that have manually been hidden and hence are not visible for people opening the spreadsheet via a link.
My sample script retrieves the showing rows from the sheet with the hidden rows using Query Language. So, about I want to fetch only those rows of a spreadsheet that are not hidden.
, this can be achieved by the sample script. From The default API call to fetch content of a spreadsheet (see my code above) fetches all the rows, even those that have manually been hidden and hence are not visible for people opening the spreadsheet via a link.
, I thought that you have tried to use Sheets API. In this case, all rows are retrieved even when the hidded rows are existing.
And from read them into a pandas dataframe.
, I thought that your goal can be achieved by modifying the sample script of this answer.
So, in order to achieve your goal, the sample script is as follows.
