how do I create a table using loops and haml with ruby?

Question

I\'m trying to make an html table that looks like this:

1 2 3 4 5
1 2 3 4 5
1 2 3 4 5

My data structure is like this: @f_ary = [ 1..250]

You should try to put all the logic for creating the rows and columns array in your controller. Rendering the view in Haml then becomes very simple:

Controller:

@items = [
  [1,  2,  3,  4,  5],
  [6,  7,  8,  9,  10],
  [11, 12, 13, 14, 15]
]

View:

%table
  %tbody
    - @items.each do |row|
      %tr
        - row.each do |column|
          %td= column

If you have a flat array of items rather than an array of arrays as in my example, you can easily convert it with flat_array.each_slice(5).to_a, where 5 is the number of columns.
