The servlet creates a table displaying the values of standard CGI variables for the current HTTP request. It stores the CGI variable names and corresponding servlet methods to access their values in a 2D string array. It iterates through the array, outputting the name and value of each variable to generate an HTML table showing all the CGI variables and their values for the request. This allows developers familiar with CGI programming to see how servlets access equivalent information from HTTP requests.
