individually specify a column, which will build up the header,
 and method or block to call on each resource in the array

 Should always be called within the block of +data+

 For example:

   t.cell :blah

 will simply call +blah+ on each resource

 You can also provide a block, which allows for other helpers
 or custom formatting. Since by default erb will just call +to_s+
 on an any element output, you can more greatly control the output:

   t.cell(:price) {|resource| number_to_currency(resource)}

 would output something like:

   <td>$1.50</td>
