A row, is a single record of one or many columns of data belonging to a table. An example, could be a customer table - that in turn has zero, one or many customer rows - one customer row could contain all the basics details of a customer

A column, is a individual data item belonging to a table. A column has a fixed datatype defined for all rows in a table. Using customers as an example again, it would be likely a customer table would include a customer name column - this column would likely be defined to record string data with a maximum width.

A table, defines a single entity within a database, and is composed of columns (that define it’s structure) and rows (which hold actual data).
