Apex inputField issue with dataTable,pageBlockTable and repeat

When working with <apex:inputField> inside dataTable,pageBlockTable with wrapper objects you have to use <apex:column> if you donot use it visualforce pahe will result inot an error saying

"<apex:inputField> can only be used with SObjects, or objects that are Visualforce field component resolvable."

To over come this you have to use <apex:inputField> inside <apex:column> or you can use <apex:repeat> instead, when you use <apex:repeat> you have to design the table structure yourself.
