reactable | Fast , flexible , and simple data tables in React | Frontend Framework library

Iam trying to create colGroups within a reactable but with changing values for the column by which i want to group. So in my example dataset the values for column group are red and blue but can change by user interaction since i want to embed the reactable in a shiny App.

The first code example provides an example with static coded colnames and this works ofc fine.

But im looking for a way to recreate the result from the first code example with not explicitly coding the colnames and i tried in the second code example.

But i cannot understand why it gives me the error Error in reactable(., columns = map(.x = seq_along(data_wider_colnames), : `columns` must be a named list of column definitions. Something must be wrong in the columns-definition; the columnGroups-definition seem to work.

The attached code should present the number of blue circles (between 0 and 4) based on the responseCount, but it doesn't. I can't see why.

I always want there to be 4 in total (blue + grey) even when the selection has a lower maximum.

I have a reactable in R and I want to display a column that is highlighted in a certain color (in the example below: yellow) and on hover each cell should display a custom tooltip which depends on a hidden (show = FALSE) column.

I have managed to do this using a workaround. I need to fill in the cells with HTML non-breaking spaces   and on hover of those space characters the tooltip is displayed.

This is not optimal, since I want the tooltip to show on hover of the whole cell and not only on hover of the spaces which are located in the cell center.

Here is my setup:

I have some data I'm trying to present using reactable. I am styling the background of cells based on the value. There are a number of groups in the data which are useful, but the groups themselves do not have an aggregated value that is useful.

The issue I'm facing is that when the data is grouped with the custom grouping select, the table will retain the style of the first few rows of data so the background is coloured. I would like it to be blank for the grouped row.

In the example below, when grouping by group you'll notice that A and C have the background coloured, inheriting the style from rows 1 and 3 in the data. I could imagine a hacky way of organizing the data so only non-stylized rows come first, but that is not really appropriate as the data would be too disorganized at initial presentation.

Is there a way to strip the style when grouped, but retain it for the rows with values?

This might seem like a silly question, but for the life of me I cannot figure it out so appreciate any help.

I am trying to pass .x (from purrr::map) to a function so in the end I get a list of functions (I will use this eventually to pass a list of column definitions with functions inside to reactable). This is a very basic example of what I want to do:

See below a very simple R shiny app that renders a reactable.

For this week's TidyTuesday challenge, I have been trying to make a table using reactable package. To this end, I looked at some blog posts on making tables with reactable in R and I made some progress, particularly with regard to customizing background colors and etc. However, although I tried for two-three days, I could not manage to add and customize titles in reactable package. The blogs I have looked at gave some examples. For instance, in one example, the following code chunk is given to make a beautiful table.

The code below produces the following table:

The Goal is to be able to select a category in the Manufacturer column (ex/ Buick) and have the 4 Models (2 from Midsize and 2 from Large) get selected. Right now the Select All feature only works by Models grouped by Type.

What I tried: ActionButton and observeEvent with updateReactable("table", selected = ...) The issue is that I want to give the users the ability to select all Models from multiple Manufacturer categories (ex/ The user selects all rows under Acura AND all rows under Buick). The action button I had tried only worked for one category and the table re-set if another button was clicked. Happy to include this failed code if it helps.

CODE:

I have an RMarkdown document which summarizes how many records (rows) have various attributes by group. I would like to be able to manipulate which records are included in the table by filtering before the summarizing. I've created a minimal but similar mockup below.

What I would like is an interactive checkbox that would effectively "comment or uncomment" out the line
