Add format to datatable conflicts with action buttons in R shiny - r

Question

I have used the directions in this other question to create a datatable with buttons inside.
I added some formatting to the renderTable() call to highlight in yellow motivation == 3
output$data <- DT::renderDataTable(
datatable(df$data) %>% formatStyle(
'Motivation',
target = 'row',
backgroundColor = styleEqual(c(3), c('yellow'))
),
server = FALSE, escape = FALSE, selection = 'none'
)
This highlights the correct row:
The problem is that color formatting messes up with the buttons. I find the same problem when trying to format dates (datatable automatically shows them in UTC and I want them on local time). Are both formatting and buttons inside the table incompatible?
I get the following warning
renderDataTable ignores ... arguments when expr yields a datatable object; see ?renderDataTable
Here's the code for the app:
library(shiny)
library(DT)
shinyApp(
ui <- fluidPage(
DT::dataTableOutput("data"),
textOutput('myText')
),
server <- function(input, output) {
myValue <- reactiveValues(employee = '')
shinyInput <- function(FUN, len, id, ...) {
inputs <- character(len)
for (i in seq_len(len)) {
inputs[i] <- as.character(FUN(paste0(id, i), ...))
}
inputs
}
df <- reactiveValues(data = data.frame(
Name = c('Dilbert', 'Alice', 'Wally', 'Ashok', 'Dogbert'),
Motivation = c(62, 73, 3, 99, 52),
Actions = shinyInput(actionButton, 5, 'button_', label = "Fire", onclick = 'Shiny.onInputChange(\"select_button\", this.id)' ),
stringsAsFactors = FALSE,
row.names = 1:5
))
output$data <- DT::renderDataTable(
datatable(df$data) %>% formatStyle(
'Motivation',
target = 'row',
backgroundColor = styleEqual(c(3), c('yellow'))
),
server = FALSE, escape = FALSE, selection = 'none'
)
observeEvent(input$select_button, {
selectedRow <- as.numeric(strsplit(input$select_button, "_")[[1]][2])
myValue$employee <<- paste('click on ',df$data[selectedRow,1])
})
output$myText <- renderText({
myValue$employee
})
}
)

Answer 1

You should look at this answer. Applying his advice to your problem, I move escape = FALSE, selection = 'none' in datatable(df$data) and it works (you need to remove server = FALSE, which is not accepted in datatable):
output$data <- DT::renderDataTable(
datatable(df$data, escape = FALSE, selection = 'none') %>% formatStyle(
'Motivation',
target = 'row',
backgroundColor = styleEqual(c(3), c('yellow'))
)
)
In case the answer I refer above is deleted (don't know if it can be), I also put it here:
You are getting this error because you are returning a DT::datatable AND you are also specifying filter='top' as one of the ... arguments to DT::renderDataTable. As the message is trying to tell you ... arguments are ignored since you are returning a DT::datatable. This is because the ... arguments are intended to be passed through to the DT:datatable constructor.
Either move filter='top' inside the DT::datatable constructor or return a data.frame and the filter='top will be used when DT::renderDataTable constructs a DT::datatable with your specified data.frame.
