how did they do this in CCK?

Here's a site that uses drupal and a job board module. The application appears to be a CCK form. Under "Education" they have what appears to be a table of fields - one label, four columns and fields in the matrix, like a spreadsheet.

How do they construct that in CCK?

Thanks.
