Hi,
This question might be related to another question I posted yesterday in relation to leaflet. I have a leaflet map and when I try and add a table via the formattable package. The table is never visible when running a flexdashboard. Below is a reproducible example. Can anyone see where i am going wrong?

title: "Reproducible Example"
output:
flexdashboard::flex_dashboard:
vertical_layout: scroll
orientation: rows

```{r setup, include=FALSE}
library(nycflights13)
library(tidyverse)
library(leaflet)
library(plotly)
library(leaflet.extras)
library(flexdashboard)
library(formattable)
library(DT)
map_data <- flights %>%
slice(1:1000) %>%
inner_join(airports, by = c('origin'='faa')) %>%
select(flight, origin, dest, orig_lat = lat, orig_lon = lon, day) %>%
inner_join(airports, by = c('dest'='faa')) %>%
select(flight, origin, dest, orig_lat, orig_lon, day,
dest_lat = lat, dest_lon = lon)
```
Airport View {data-navmenu="Report View"}
=====================================
Row {data-height=600}
-----------------------------------------------------------------------
### Outbound Maps
The Total Number of airports for this report is `r length(unique(airports$name))`
```{r}
# We generate layers based on the airports
ob_data <- map_data %>%
split(., .$origin)
objleaf <- leaflet() %>%
addTiles()
names(ob_data) %>%
purrr::walk(function(df) {
objleaf <<- objleaf %>%
addMarkers(data=ob_data[[df]],
lng=~orig_lon, lat=~orig_lat,
popup=~as.character(origin),
group = df,
clusterOptions = markerClusterOptions(removeOutsideVisibleBounds = F),
labelOptions = labelOptions(noHide = F, direction = 'auto'))
})
objleaf %>%
addLayersControl(
overlayGroups = names(ob_data),
options = layersControlOptions(collapsed = FALSE)
) %>%
addResetMapButton()
```
Row
-----------------------------------------------------------------------
### Random table for Outbound
```{r}
flight_table <- map_data %>%
group_by(origin, dest, day) %>%
summarise(flights = n()) %>%
spread(day, flights, fill = 0)
q <- as.datatable(formattable(flight_table,
list(area(col = 3:ncol(flight_table)) ~ color_bar("lightgreen"))))
q
```
Airport View {data-navmenu="Report View"}
=====================================
Row
-----------------------------------------------------------------------
### Inbound Maps
The Total Number of airports for this report is `r length(unique(airports$name))`
```{r}
# We generate layers based on the airports
ib_data <- map_data %>%
split(., .$dest)
objleaf <- leaflet() %>%
addTiles()
names(ib_data) %>%
purrr::walk(function(df) {
objleaf <<- objleaf %>%
addMarkers(data=ib_data[[df]],
lng=~dest_lon, lat=~dest_lat,
popup=~as.character(dest),
group = df,
clusterOptions = markerClusterOptions(removeOutsideVisibleBounds = F),
labelOptions = labelOptions(noHide = F, direction = 'auto'))
})
objleaf %>%
addLayersControl(
overlayGroups = names(ib_data),
options = layersControlOptions(collapsed = FALSE)
) %>%
addResetMapButton()
```
Row
-----------------------------------------------------------------------
### Make Some Random Table for IB
```{r}
flight_table <- map_data %>%
group_by(dest, origin , day) %>%
summarise(flights = n()) %>%
spread(day, flights, fill = 0)
q <- as.datatable(formattable(flight_table,
list(area(col = 3:ncol(flight_table)) ~ color_bar("lightgreen"))))
q
```
