How to pass the data from a table to variables?

[arturion]

How can I identify the text of a <td> and pass it to a variable? How to add rows to an existent table, pushing a button? Is there a function or a tutorial about it?

You can do this using DOM (Document Object Model) functions. Check the attachment for a commented example. I tested it under Mozilla 1.6a and Opera 7.23, it fails in IE6, however (because IE doesn't support many DOM functions, Web standards, or anything else for that matter).
