Inline Editing in PageBlockTable

I was eager to know about inline editing in page-block table as we usually see on simple Native pages.so I studied about this decent feature of Salesforce and tried at my end as below:

I practiced with simple Sobject Account.

VF Page code:

Controller code:

public class InlineEditing
{
   public List getListofAccounts()
   {
       List accTempList = new List([select id,Name,Industry from      Account order by LastModifiedDate ASC limit 5  ]);
       return accTempList;
   }
   public InlineEditing(ApexPages.standardController sc)
   {
       
   }
}

Thanks for visiting.
