title: ruby / splitting array into columns
body: <p>I could've found out using the right naming, but so far nothing popped up. I'd look into splitting an array into columns.</p>
  
  <p>Meaning, having <code>[0,1,2,3,4,5,6,7,9]</code>, I'd like to have 4 arrays (4 columns) :</p>
  
  <p><code>[ [0,4,9], [1,5], [2,6], [3,7] ]</code></p>
  
  <p>Practically, I'd look into iterating over an active record array, displaying those (they're images records) in 4 different html columns, while maintaining their order from left to right</p>
