Add Single Record From Other Page?
I'm afraid your question is not clear to me. Could you kindly explain more in detail what you'd like to do?
Display an input box on a page.
Type data into the inputbox.
Click Submit button, and a record gets added to a table, containing the data i typed.
Type new data into the inputbox.
Click Submit button, and another record gets added to the table.
DataTable2 works by parsing data from wikipage text. To make your idea work, you'd need an inputbox which inserts a record into the text of a page. I'm afraid I'm not aware of the existence of an inputbox of this kind.
