Overview

Create an html table from a collection of data.

Typically this will be a collection of models of the same type. Each member of the collection must respond to the column names provided.

Example:

“‘ruby table_for(:people) do |t|

t.column :name
t.column :email
t.column :phone

end “‘

This assumes that a @people variable will exist in the view and that it will be a collection whose members respond to :name, :email, and :phone

This will result in markup like the following:

<table id="people">
  <thead>
    <tr>
      <th class="name">Name</th>
      <th class="email">Email</th>
      <th class="phone">Phone</th>
    </tr>
  </thead>
  <tbody>
    <tr id="person-1">
      <td class="name">Steven Talcott Smith</td>
      <td class="email">[email protected]</td>
      <td class="phone">415-555-1212</td>
    </tr>
  </tbody>
</table>
