I am making a small app in Shiny, however I believe that this issue can fixed with just some Javascript knowledge.
I am using the excelR package with Shiny to display some tables. This package is simply using the jexcel/jspreadsheet plugin and translates it into useable R functions - as such, the underlying javascript of the app is the same as a website using vanilla javascript.
How can I prevent the column headers to follow the scroll like in the gif above? I cannot seem to find the documentation for that specific behaviour, so I was wondering if there was a way to overwrite the Javascript for it perhaps?
