Ruby - Iterate over array and create a three column, x rows table

Question

In a view, I get an array of objects. I want to have a three column table that will be filled with an attribute of those objects. So, if my list has 5 objects, my table will have two rows: the first row will contain three cells, and the second row 2 cells.

How do I iterate over that list in order to accomplish this?

This is one big long non-sequitur. How do you get from 5 objects to only two rows? — Mark Fraser

It would be better to post what you have attempted so far and tell us where you're stuck. Here is a hint..you will want to start a new row when n % 3 is 0. 'n' being your current position in the array. — Mark Fraser

If you really want to use tables and just iterate over your array you could use each_slice and go over the returned arrays, like your_array.each_slice(3)

But you could also not use tables, use some divs for example, and iterate over your big (5 objects) array and style the divs so that they fit 3 in a row.
