Design Table Basics

I have been working in SolidWorks for just over a year and I need some help understanding the basics of using Design Tables.  My background is in Pro/E and I had a good understanding how to use "Family Tables" to create parts, assemblies and drawings.  For some reason I am having a great deal of trouble understanding DT.  Any suggestions on where to look for help...website, previous post, ect

Thanks in advance.
