A few questions regarding creating web pages (using Dreamweaver 4.0)

1. What is the difference between the readonly and disabled properties for input fields?

2. Is there any easy way to disable (or make readonly) all objects in a HTML page (or within a form on a page) without having to manually add the 'disabled' property to all objects on the page?

3. On more than one occasion I have wanted to split a table into 2 separate tables.  Apart from physically creating the new table, then transferring all cell contents from the original table to the new table, is there any easy way to do this?

Many thanks,
