Exams - Sort Table

/* You are given a HTML table with 3 columns: product, price and votes. Write a JavaScript function to sort
the table rows by price (as number, increasingly). The input is passed to the first JavaScript function
found in your code as array of strings in the format of the examples below. The HTML table will always have
a header row and 3 columns: product, price and votes. No whitespace will be found between the tags
and between the tags and the tags values. When several rows hold equal prices, use the product name
as second sort criteria (sort by product name alphabetically).*/
