How can I reduce row height in DT datatables

问题

I would like to be able to get 'slimmer' rows when rendering a DT datatable (ie decrease that height)

options(digits.secs=6)
library(data.table)
d = data.table(x = 1:10,time = as.POSIXct('2015-03-23 12:00:00.123'))
library(DT)
datatable(d)

If you add the pageLength= attribute you can set how many rows to show initially. And by adjusting the lengthMenu= c() you can also control the sizes of offered in the drop down, You can also turn search on or off with searching =FALSE

   library(DT)
    datatable(d, options=list(
       pageLength = 3,
       lengthMenu = c(2, 12, 18),
       searching= FALSE))%>%

   formatStyle( 0, target= 'row',color = 'black', backgroundColor = 'yellow', fontWeight ='bold', lineHeight='70%')

And by using the helper functions you can set the style just as you would in traditional CSS on a webpage. Notice the last one, line-height should adjust the row height.

Edited: I moved all the code together for you to see how it works. Sorry I was not clearer up front. The %>%is necessary as is devtools::install_github("rstudio/DT") version of DT.
