Subject: ruby on rails or sinatra for dynamic browser application

I need to write a simple html file or web application that will allow me
to display the contents of a text file in a browser. This will involve
some formatting and eventually some dynamic features like sorting. This
is tabular data, so I am more or less creating a spreadsheet display in
a browser. I don't know how to display a variable amount of data in
html. I can hard code things, but for this application, the number of
rows and columns will be variable.

I want to use ruby because I am using ruby to access a sqlite database
from which the text file is created. Eventually the text file will go
away and the application will just show data that is queried from a
database. It makes sense to use ruby for the dynamic code on the webpabe
if I am using it to access the database. I know that both ruby on rails
and sinatra are used to create web pages, but I don't know much more
than that.

Can someone point me to a tutorial or example of how to do something
similar? Basically the application needs to open a text file (possibly a
browse button on the webpage to give it a path), read the file into
variables, and then use the variables to populate rows in a display.

Am I on the right track here?
