Drag and Drop is from JavaScript the definitive guide by David Flannagan
http://www21.brinkster.com/sturman/js/portableDrag.js The dynamic table is something I wrote.I have an updated version that has more features.
This early version not very good but you are welcome to it...maybe you can use it as an example to create your own.
http://www21.brinkster.com/sturman/js/dtable.js The main changes I made to the dynamic table object was to add many prototype methods for setting style and handling events.These can be overridden so that each cell of a table can be customized as far as how content is computed or how the cells style is set.
In general,I recommend javascript the definitive guides 4th edition by David Flannigan.
