如何创建动态SQL表ASP.NET？

I am trying to create a website using ASP.NET, Microsoft SQL and C#. I am creating a food recipe site where the users can upload their own recipes. In the recipe submitting form there are the ingredients section and the steps section. The data collected in the form is sent to a SQL DB table. However the number of steps and ingredients is indefinite. So how to I add it to the table. Is it possible to create a dynamic table. Any kind of help is much appreciated.I am trying to create a website using ASP.NET,
