Using R shiny & DT package, I am creating certain tables. The number of columns vary as per user input & is not fixed. I have included the following code snippet to include a horizontal scrollbar so that when the number of columns is large, the user can scroll through the columns that are not directly visible.
server.R:
output$results <- DT::renderDataTable({
DT::datatable(data = datasetInput(),
options = list(scrollX = TRUE,...)
)
})
<code reduced for brevity>
Using the above code, the Horizontal scrollbar is not visible at first but appears when I click on a row and hit right arrow on my keyboard. Is there any way the scroll bar becomes visible as soon as the table is fired up, no matter how many columns I have, and I can drag the scrollbar using the mouse pointer?
Update:
I tried the code in the answer below and this is what I see - no horizontal scrollbar.
I don't think you can (or should) force a scrollbar easily if you don't need one, but the above code works fine for me, it shows a scrollbar when the page initializes. Maybe the problem is with the data or something else.
Here's a minimal example that has a horizontal scrollbar on page load
