title: Change the default size of the Search Box in DT:: datatable in Rmarkdown
body: <p>I have tried searching a method / options in DT::datatable to change the default width of search box. Answers available are for HTML/CSS etc but I am not sure how to incorporate the width = 200px or 200% in options =list(search = list(search="",
  width = 200px # or width = "200%" is not working.</p>
  
  <pre><code>DT::datatable(
    mtcars,options = list(dom="ft",search =list(search = 'Type here to search',
    width= "200%")))
  </code></pre>
  
  <p>Any guidance on dom elements in DT will be appreciated. Thanks.</p>
