Sui | Modern super user interface implementation on Android

I'm a beginner in laravel and I'm trying to create a form and submit it to the database.

I managed to save the data to the database using the following code.

My Blade :

I want to edit the update counter from both add and remove button.

Unfortunately, the delete button doesn't update it even if the add button works well as requested.

There is a picture below to show my issue.

here is the code on codesandbox which is simpler: https://hq5lf.csb.app/

Here is my code:

I store the result of my Flask server in this.state.jsondata and it's a JSON like this {label{},text{}}

My scenario is the following one: the client upload a CSV to the Flask server, Flask convert the CSV to a Pandas dataframe in order to perform task then it send it back as a JSON object, finally the client display the result in a

My problem is : Objects are not valid as a React child (found: object with keys {label, text}). If you meant to render a collection of children, use an array instead.

So after some research I understand that the problem comes from the way I transfer the data from Flask to the client.

Here is my Flask code:

I have a problem, when I delete my array from localStorage it works, but when I add a new option the previous option reappears. I am using localStorage.removeItem('arrayOption') , how to permanently delete it ? thank you for help

I'm trying to calculate how many times a value occurs in a specific location inside a data frame.

As an example I use this data frame:

I want to apply the following css to just a part of an image, let's say 50% of the image, is there any way to do that?

Given a small test data as follows:

For statistical analysis in performance sports, I often collect data form https://www.fis-ski.com/en and import it to MS Excel by copy/paste, before I work on it in RStudio. As FIS updated its website structure recently, the imported data shows up in one column and it is not possible to convert it back to a structured table via "text to columns". I tried it also by using a macro but as the imported data doesn`t have a uniform structure, because missing data (NA´s) are not shown as empty cells, converting data is quite tricky for me as a "non-programmer". The data I would like to extract are the following:

https://www.fis-ski.com/DB/alpine-skiing/biographies.html?lastname=&firstname=&sectorcode=AL&gendercode=M&birthyear=1980-2004&skiclub=&skis=&nationcode=SUI&fiscode=&status=&search=true

...but as I need the results of every single athlete in this list, here an example...

https://www.fis-ski.com/DB/general/athlete-biography.html?sectorcode=AL&seasoncode=&competitorid=230012&type=result&categorycode=&sort=&place=&disciplinecode=&position=&limit=1000

..., I have a lot of data which I need to get in order! So, I have two questions:

1. Is there a easy method to get the copied data back in order as a table?
2. Is there a way to extract the results-data from all athletes (SUI, male, YoB 1980-2004) without switching from athlete to athlete?

Thank you very much in advance... looking forward to your answers...
