rhandsontable | A htmlwidgets implementation of Handsontablejs | Data Visualization library

I need to format rows of a pivoted table using RHandsontable. Column formatting is super straightforward, but hot_row() does not provide the same flexibility as hot_col().

Has anyone figured out a way to format this...

I would like to display a scaled-up popup image on mouseover or on-click event on an image displayed in the rhandsontable cell similar to as shown here in DT table.

I would like to display the popup image for the image displayed in the table created as shown below:

I am working on the R shiny app. I have created Tab1 and Tab2 in Shiny, and what I am attempting to do is make the datatable visible in "Tab2" once I fill in the below forms and hit the "Add" button.

Summary

When the user enters information on "SchoolId, UserId, class, result" in Tab1 and clicks the "Add" button, the Datatable in "Tab2" should appear.

Also, once the user presses the "Add" button, the fields "SchoolId," "UserId," and so on should be empty, ready for the user to fill in the data of the second row in "Tab2."

Issue:

I am sure that I am missing something here to build a server-level connection for the "Add" button, because I can't fill in the details for the second row in Tab2 because since "Add" button is not working.

Could someone help to fix this issue?

I am trying to display images in a rhandsontable. The images are of various sizes. I would like to normalize the display size of the images to a single size. In this regard, I need help with how to adjust the display size of the image in a rhandsontable.

I am trying to hide some columns of a tibble (that's created using a function) from appearing in the console window in R studio. I'm not sure if this is even possible!?

Similar questions have been asked here and here. However, these examples take a data frame and output the final edited version of it to the Viewer window. I don't want to display my data frame in the Viewer window.

Below is a toy example of what Im trying to do.

In my code, I have 2 functions. The first function takes some data and does some manipulation (including adding some new helper columns to the data) and outputs a tibble. I then pass that tibble to the second function which does more data manipulation by using the helper column. Im trying to hide the helper columns that are created in the 1st function from the user (by not displaying them in the console window). But still allow them to be used by the 2nd function.

For example:

I am trying to create a table using rhandsontable with several rows of merged cells (different cells in each row).

I am trying to achieve merging of the indicated cells in the screenshot below ...

I am able to successfully merge the first set of cells (row 11) but subsequent merges using a "list of lists" to specify the cells doesn't work. I have tried every permutation of the "list of lists" syntax that I can think of;

a reprex of the example is here ...

I have a table, in which the user will give as input some groups. As a result, I want another column to automatically update and show the frequency (or replicate) of each group:

This code creates this app:

I am currently working on a project using in which I need to import an export a data frame as a .csv file. Here is the code:

ui.R

I want to change the colour of the whole row when the user unchecks a checkbox present in one of the cells. (Could be multiple rows)

So far I'm only able to change the colour of the cell containing the checkbox rather than the whole row. In this example, the whole row 6 should be coloured.
