Hello Roy and welcome to the forum.
Tables are "made on the fly" so to speak. They can be sized; fields can be merged; and limited formatting can be done for the containing text. Just look under the table tab in Creo (I'm assuming you are a Creo user) to get started.
Sketching is another matter. There are several drawing tools and translation tools. Helpful tools like grids and grid snap as well as sketching "helpers" will make a tedious job a little easier.
I know there must be some pretty good videos on how this stuff is done. You probably have access to the knowledge base. I would recommend beginning there, or the learning connector.
I am also going to ask what your end game is. What is it you are trying to accomplish. If you want to make formats with variables as format files rather than just drawings, you will also want to search the forum for helpful tips on how to make these.
Your question can become a huge subject, so if you can help narrow it down, we might be able to provide specific links to more targeted topics.
