How can I refresh a DataTable from a file after the file has been updated in Shiny

[Birdman]

I have a Shiny app where the user through the choices in the app builds a requirements table, once they have added all the information they hit a button to run my R code that generates a new table and saves a file. How can I update my mainPanel with the updated datatable or file? I would like it to just refresh on the screen once the file (or table) is created.

Oh, I should add, I am using the observeEvent on the serverside to run the R code.

Thanks

Hi, can you provide a reproducible example?
based on what you have described, you can insert a tableOutput in the UI, and then you update this output inside the observeEvent usingrenderTable.
So if your tableOutput is called mytableoutput, the code will be something like:
observeEvent(input$mybutton,{
mytable = ... # generate the table
....
output$mytableoutput = renderTable(mytable)
})
