I have a problem with text in Shiny Dashboard. I would like to save original text formatting, but shiny removes the whitespaces I want to keep.

output$frame <- renderUI({
    HTML(paste(
               p(strong("Name and Surname:"),("     John Smith"))
               )
         )
  })


tabItem(tabName = "aaa",
        h2("bbb"),
        fluidRow(
                box(width = 6, solidHeader = TRUE, htmlOutput("frame")) 
                )
      ),

Unfortunately I get "Name and Surname: John Smith". I wish to have "Name and Surname: John Smith".

How to solve this problem?

You can use HTML('&nbsp;') to add 1 whitespace and HTML('&emsp;') to add 1 tab space. In your code it wold be as follows:

output$frame <- renderUI({
        HTML(paste(
          p(strong("Name and Surname:"), HTML('&nbsp;'),HTML('&nbsp;'),"John Smith")
        )
        )
      })

With this you get two white spaces and output looks like this:

shiny fluidrow column white space, shiny fluidrow column white space � r shiny whitespace. I have a top banner that I want to split into two separate sections representing two� The .noWS parameter can take one or more other values to control whitespace in other ways: "before" suppresses whitespace before the opening tag. "after" suppresses whitespace after the closing tag. "after-begin" suppresses whitespace between the opening tag and its first child.

I found that we can also use stri_dup(intToUtf8(160), 6) from package stringi.

I found this oddly difficult to achieve. Just adding the style element to pre-wrap introduced an extra new line:

p(strong("Name and Surname:"),("     John Smith"),style="white-space: pre-wrap")

No other style elements (margin:0, etc) could fix this...so,to get around it, I just converted your strong() to HTML, and it works great:

p(HTML("<b>Name and Surname:</b>         John Smith"),style="white-space: pre-wrap")

The easiest way to describe them is by running through an example. Paste the ui object below into your app.R file and save it.

Shiny developers can provide this document as an index.html file or assemble it from R code in their ui object. The UI calls R functions that output HTML code. Shiny turns this code into a web app. I will use the 01_hello app throughout this article as an example. You can access this app

  • Shiny probably doesn’t remove anything. But whitespace in HTML isn’t preserved — that’s just the way HTML works. Use CSS formatting instead of whitespace to align your elements.
