How to create an html table with Jade iterating an array

I found that the problem was that I was missing the TD tag for each TR. So the jade code should be like this:

div
  table
    thead
      tr: th Posts
    tbody
      each post, i in userPosts
        tr
          td 
            a(href='/admin/post/' + post.id) #{post.author} - #{post.title}

try this

div
  table
    thead
      tr: th Posts
    tbody
      each post, i in userPosts
        tr(class=(i % 2 == 0) ? 'odd' : 'even') 
          td
            a(href='/admin/post/' + post.id) #{post.author} - #{post.title}
