This is most easily achieved by using the rhandsontable html widget package. Let's take a look at how we do that by going to our exercise files, folder 0704, and we'll open our R Studio project. Let's open our server.r file, and our ui.r file as well, and let's run our app to see what we're dealing with.

If I wanted to add additional rows to my table, I'd right-click in a row, and click insert row below. Now if I click on analyze data, what I want to happen is a chart to appear below which tells me information about the data I've inputted.
