DT extension

[Jason Ji]

Hi all,

I am now incorporating DT in my shiny apps. I want to use multiple extensions in my DT, so I set options to be a list. For example, I want to use Colvis extension. The syntax I used was: 

DT::datatable(Maindata$showres,escape = F,filter='top',rownames = F, extensions = list(ColVis = list(dom = 'C<"clear">lfrtip')))

However, the ColVis extension did not function. I wonder whether there is something wrong with this syntax? Thanks!

Please see the first two paragraphs at
http://rstudio.github.io/DT/extensions.html In your example, you did
not really use multiple extensions, though.
