This gem was extracted from some projects on my company. Everyone is welcome to use and improve upon.


Add this line to your application's Gemfile:

gem 'html_tables'

And then execute:

$ bundle

Or install it yourself as:

$ gem install html_tables


Slim example:

= data_table_for(@products, name: :products_table, html: { class: 'custom_table' }) do |t|
  - t.group_by(:category) do |cat|
  - t.column(:code, align: :center, width: '9em')
  - t.column(:description) { |p| p.descriptions.first }
  - t.column(:pricing, footer: :sum) do |item, total_in_footer|
    - if item
      = number_to_currency(item.pricing)
    - else
      blink = number_to_currency(total_in_footer)
  - t.column(:quantity, width: '9em') do |p|
    - if p.quantity == 0
      span title='Out of stock' *
    - else
      = number_with_delimiter p.quantity
  - t.column(:status, align: :center, width: '3em', header: { text: 'St.', class: 'status-header' })
  - t.nodata 'No product found.'
