I am working on a simple dashboard with using R, Shiny, Flexdashboard and Leaflet. The code itself seems to work fine. However I am facing some issues to deploy it.
When I run/Knit the document for the first time everytyhing seems ok, but if I try to publish it I receive this message when I hit the 'Publish' button above the rendered document:
'Only rendered R Markdown documents can be published to RPubs. To publish this document, click Knit to render it, then click the Publish button above the rendered document'
Then, if I reload the page or Knit the document again without make any change, the tables and the maps disappears.
Initially, I thought it was something with Leaflet, but I got the same behavior with this minimal and reproducible example both in R Studio and R Studio Cloud.

title: "Example"
output:
flexdashboard::flex_dashboard:
orientation: columns
runtime: shiny

```{r }
library(flexdashboard)
library(shiny)
library(DT)
# OPERAÇÃO POR BAIRROS
link = "https://docs.google.com/spreadsheets/d/e/2PACX-1vS3cj3PhVm-2F-CiEJOE8O1YIIU6t7os_wDDrACFne39ZRUvxLKdV_MKZNzD6xTG0hoI5ZroHpxyIzV/pub?output=csv"
df_op = read.csv(link)
```
Column {data-width=350}
-----------------------------------------------------------------------
### Table
```{r table}
df_table = reactive({
df_op
})
DT::renderDataTable(df_table())
```
To solve the blank element issue, the line runtime:shiny must be written from the first column, just as described bellow.
