Ask HN: Questions on building a app page

Hi all, im quite new to programming so pardon me if my question sounds elementary. I am trying to apply what Ive learnt to a simple dummy page with RoR and PGsql.<p>Im wondering if its possible to build something that looks similar to Google spreadsheet on a input page (i.e I can input from a web browser) which translates to a output page as compact lines or grids?<p>The input and output page formats are limited (I think from CSS Boostrap), ie. they appear as single line forms which cant be inputted on a side by side basis (i.e I have to input based on text boxes for all of one column, say all countries first, then the next.) Can&#x27;t we do it both vertically and horizontally together? (Reason being its easier to input and check for the accuracy of the information).<p>Also good to have a auto calculation such as total population etc which refreshes.<p>So something like for example:<p>Country City Population(mm) Weather Remarks +add more categories US NYC 8.4 stormy Nil US CA 38.0 sunny<p>Any help is much appreciated! Thanks!
