We wish to sort the rows of a table by the values of one or more columns and we wish to identify the columns to use for
sorting by explicitly specifying their name.
In this section we will cover three scenarios of table sorting:
Single Column where we cover how to sort a table in
ascending or descending order of the values of one column.
Multiple Columns where we cover how to sort a table
in ascending or descending order by the values of multiple columns. When sorting by multiple columns, sorting is
carried out in order where rows that have the same value for a former column are sorted by the value of a later
column.
