Whitespace in rendertable output on ShinyDashboard - r

Question

I am creating a table using renderTable and a plot (plotly) to be placed in ShinyDashboard. There is a whitespace that surrounds the table data that I am trying to get rid off. However, there is no whitespace around the plot.
How do I remove the whitespace that surround the table i have added to my shiny dashboard.
How do I align the header of the table "Recruitment" to the center?
I know there are some HTML solutions, but I am not familiar with those codes and will be glad if someone can explain.
Here are my codes:
Server codes
output$recruit_stats <- renderTable(recruit_stats, bordered = TRUE, colnames = TRUE)
output$Recruitment_bar_plot <- renderPlotly({
Recruitment_bar<-Recruitment_bar[(Recruitment_bar$hospital!="H"),];
R01 <- ggplot()+
geom_bar(data=Recruitment_bar,aes(x=hospital,y=count),stat = "identity", fill="navyblue")+
ylim(0,1200) +
geom_text(data=Recruitment_bar,aes(x=hospital,y=count*1.05,label=paste(count)),size=2.5, vjust=-1.0) +
theme(panel.background = element_blank(),
axis.text = element_text(size = 7),
axis.title = element_text(size=7),
axis.line = element_line(colour = "black", size = 0.5, linetype = "solid"),
plot.title = element_text(size=8, face="bold", hjust=0.5),
legend.position = "none", legend.text = element_text(size=6)) +
labs(fill="") + guides(fill = guide_legend(reverse=TRUE))+
ylab("No. Recruited") + ggtitle("No. of Patients Recruited (Jan 2017 to June 2018)")
ggplotly(R01, tooltip=c("count"));
})
UI codes
Recruitment<-tabItem(
tabName = "Recruitment",
fluidRow(
box(
box(title = "Recruitment",
status = "primary",
solidHeader = TRUE,column(12,tableOutput("recruit_stats"), align="c"),
width=8,
collapsed=TRUE)
),
box(
plotlyOutput("Recruitment_bar_plot", height = 400),
width=5,
status = "primary",
solidHeader = TRUE
)
)
)

Answer 1

I would drop boxes and try grid by columns. For table have a look at DT tutorials.
library(shiny)
library(shinydashboard)
dat5 <- c(rep("Female", 3376), rep("Male", 2180))
app <- shinyApp(
ui <- shinyUI(
dashboardPage(dashboardHeader(title = "PSM"),
dashboardSidebar(),
dashboardBody(
tabItem(
tabName = "Recruitment",
fluidRow(
column(width=6,
DT::dataTableOutput("recruit_stats")),
column(width=6,
plotOutput("pie_chart", height = 400))
)
)
))
),
server <- shinyServer(function(input,output){
output$pie_chart <- renderPlot({
df <- table(dat5)
cols <- rainbow(length(df))
barplot(df, col = cols)
})
output$recruit_stats <- DT::renderDataTable({
DT::datatable(as.data.frame(dat5), options = list(paging=TRUE, searching= TRUE ))
})
})
)
runApp(app)
