Rails - Jul 2008 - How to set row height in active scaffold html table?

I have a products table created in active scaffold and html table
display is fine.But the product descriptions are too long for some
products and it stretches the html TD cell.

Now I want to limit the TD height and make the rest of description
content hidden by adding <div style="height:30px;
overflow:hidden">
</div> to the TD contents. That is:
...<td><div style="height:30px;
overflow:hidden">Product_descriptions</div></td>


My question is how I can do this customization?

TIA,

Daniel

I figure this out by myself:

module ProductsHelper
  $tag_start = "<div style=''height: 30px; overflow:
auto;''>"
  $tag_end = "</div>"

  def description_column(record)
      description =  $tag_start + record.description
      description += $tag_end
  end
end
