title: How to use library(writexl) pakcage to save multiple dataframe with a custmized name
body: <p>I am using the package writexl to save two dataframe into one csv file in R shiny. </p>
  
  <p>And here is part of my code:</p>
  
  <pre><code>library(writexl)
  server &lt;- function(input,output){
      filename = function(){
                paste('data.csv')
              },
      content = function(file){
      df1  &lt;- ...
      df2 &lt;- ...
      write_xlsx(list(df1,df2), file) 
          }
        )
  </code></pre>
  
  <p>this code works for me but do you know how to give a customized sheet name for df1 and df2? I don't want to change the package, would just want to use "write_xlsx", not the "write.xlsx"</p>
