title: WPF window that looks like excel
body: <p>I am new to WPF and c#, and I am trying trying to create an excel like table with a fixed number of columns and a varying number of rows according to the user's needs.People advise to use a datagrid, but I am very confused, some say that it is used mostly to display data source content (which is data contained in database if I understood). I read also about listviews, binding things to itemsource...etc. This is really a lot of information to work with! What I simply need is a way to create a table with fixed columns, and adding rows automatically when the user clicks on a button, that's it! No binding, or anything of this sort.But how to achieve that? Also, if you have good websites tutorials for working with datagrids, I would be very grateful (most of those that I found are too much complex, or don't explain well).</p>
  
  <p>Thanks a lot!</p>
