2010 working with designer

I am working with a new web form page in C# 2010. Within this web form, I am creating a web form table. Thus working with this web form table, I would like to know the following:

1. If I want some rows in the table to be blank (basically skip some a row for placment), how would I do this?

2. Within the table in certain cells, I want to drag and drop items from the toolbox like a label and textboxes. Can you tell me how to do this with the visual desinger? If this is not possible, can you tell me another way to meet my goal?
