What replaces cellpadding, cellspacing, valign, and align in HTML5 tables?

In Visual Studio, I'm seeing these warnings:

• Validation (HTML 5): Attribute 'cellpadding' is not a valid attribute of element 'table'.
• Validation (HTML 5): Attribute 'cellspacing' is not a valid attribute of element 'table'.
• Validation (HTML 5): Attribute 'valign' is not a valid attribute of element 'td'.
• Validation (HTML 5): Attribute 'align' is not a valid attribute of element 'td'.

If they are not valid attributes in HTML5, what replaces them in CSS?
