I have this code which prints multiple tables

Given MySQL tables something like this¹:

I have a list (dput() below) that has 4 datasets.I also have a variable called 'u' with 4 characters. I have made a video here which explains what I want and a spreadsheet is here.

The spreadsheet is not exactly how my data looks like but i am using it just as an example. My original list has 4 datasets but the spreadsheet has 3 datasets.

Essentially i have some characters(A,B,C,D) and i want to find the proportions of times each character occurs in each column of 3 groups of datasets.(Check video, its hard to explain by typing it out)

I have the following two interfaces, one which allows a nullable vin, the other that doesn't:

Update: Added a simpler demonstration jsfiddle, https://jsfiddle.net/47sfj3Lv/3/.

reproducing the problem in much less code I'm trying to move away from jQuery.

Some of my code, for populating some tables, has code like this

The minimal reproducible code below aims to have a loading icon when a button is pressed(to simulate loading when asynchronous computation happen).

For some reason, the Consumer Provider doesn't rebuild the widget when during the callback.

My view:

I have a dataset with the name of Danish ministers and their position from 1990 to 2020 (data comes from dataset called WhoGovern; https://politicscentre.nuffield.ox.ac.uk/whogov-dataset/). The dataset consists of the ministers name, the ministers position, the prestige of that position, and the year in which the minister had that given position.

My problem is that some ministers are counted twice in the same year (i.e., the rows aren't unique in terms of name and year). See the example in the picture below, where "Bertel Haarder" was both Minister of Health and Minister of Interior Affairs in 2010 and 2021.

I want to create a dataset, where all the rows are unique combinations of name and year. However, I do not want to remove any information from the dataset. Instead, I want to use the information in the prestige column to combine the duplicated rows into one. The observations with the highest prestige should be the main observations, where the other information should be added in a new column, e.g., position2 and prestige2. In the example with Bertel Haarder the data should look like this:

(PS: Sorry for bad presenting of the tables, but didn't know how to create a nice looking table...)

Here's the dataset for creating a reproducible example with observations from 2010-2020:

I have a custom slide toggle component created using Angular Material. I followed this guide: https://material.angular.io/guide/creating-a-custom-form-field-control

Everything seems to be working fine except when I dynamically disable the custom component like this:

I'm trying to create a multi-level dropdown using Bootstrap and some JSON data.

Ideally, I want the dropdown to have this kind of nested functionality:

I'm working with an array of objects with nested data, and it looks like:
