Table Class allows you to create highly dyanamic HTML tables easily and quickly. It supports CSS, any number of arbitrary tags, and creating tables inside tables. This class is useful for implementing intensive reporting features. Table Class is faster than using and parsing traditional HTML templates because the class works completely in memory, storing all the table data in several comprehensive arrays, while not compiling to HTML until you want it to. This allows for dynamic editing of any attribute of any element. Rows and columns can be easily added and subtracted at any time, and row contents can be added simply by passing an array.

PHP Generator of Object SQL Database generates objects from the description of table in an SQL database. Each object map is a table in the SQL database, and has methods to insert, modify, and delete an entry in the database. But they also have methods to show forms, and to get data after an HTTPD post, or a get. They have iterator methods, and call your function for each entry of your request. Some templates help you to write HTML forms. This can help when you change databases, as the API is the same all the time, and you don't have to patch the PHP objects, but just regenerate them.
