Rotate headers of a reactable in R Shiny

Solution 1:

Not sure what your expected result looks like, but how about this:

library(shiny)
library(reactable)

ui <- fluidPage(reactableOutput('rt'))

server <- function(input, output) {
  output$rt <- renderReactable({
    reactable(
      mtcars[1:4, 1:5],
      fullWidth = F,
      defaultColDef = colDef(
        align = "center",
        minWidth = 70,
        headerStyle = list(
          `white-space` = "nowrap",
          `transform-origin` = "50% 50%",
           transform = "rotate(-90deg)",
          `margin-top` = "10px",
          `margin-bottom` = "10px",
           borderColor = "#ffffff"
        )
      )
    )
  })
  
}

shinyApp(ui = ui, server = server)
