How to populate a table with data vertically?

Question

I have three arrays I'd like to arrange vertically in an HTML table. Each array will have its data populated in a column from top to bottom.

For example, I have three arrays:

fruit = ['pear', 'apple', 'orange']
veges = ['corn', 'radish', 'lettuce']
meat = ['beef', 'chicken', 'pork']

I want the table to look like this:

<table>
  <tr>
    <td>
      pear
    </td>
  </tr>
  <tr>
    <td>
      corn
    </td>
  </tr>
  <tr>
    <td>
      beef
    </td>
  </tr>

  <tr>
    <td>
      apple
    </td>
  </tr>
  <tr>
    <td>
      radish
    </td>
  </tr>
  <tr>
    <td>
      chicken
    </td>
  </tr>

  <tr>
    <td>
      orange
    </td>
  </tr>
  <tr>
    <td>
      lettuce
    </td>
  </tr>
  <tr>
    <td>
      pork
    </td>
  </tr>
</table>

Answer 1

I'd probably use Array#transpose to rearrange things to match what your <table> should look like:

rows = [ fruit, veges, meat ].transpose

Now rows will look like:

[
  ["pear", "corn", "beef"],
  ["apple", "radish", "chicken"],
  ["orange", "lettuce", "pork"]
]

and generating your table is a simple matter of iterating over rows:

%table
  - rows.each do |row|
    %tr
      - row.each do |food|
        %td= food
