Rows. Each row in a database table represents one instance of the type of object described in that table. A row is also called a record. Columns. The columns in a table are the set of facts that we keep track of about that type of object. A column is also called an attribute. Example. The Instructors table.
It isn't possible to define columns based on row data. Imagine that row 1 has 2 columns, row 2 has 6 columns, row 3 has 1 column, etc how would you ever produce a technically valid table in HTML? Each row must have the same amount of columns.
