Can't create a table with the same name I deleted before
you can do something like this, it will create and drop a table called t1, schema dbo

use tempdb
go

--------------------------------------------------------------------------------
-- creates the table
--------------------------------------------------------------------------------

if exists (
              select * 
              from sys.tables t
              inner join sys.schemas s
                      on t.schema_id = s.schema_id
              where t.name = 't1'
                and s.name ='dbo'
          ) 
          begin

              drop table dbo.t1
               print 'table dropped'
          end 
else
          begin

               create table dbo.t1 (i int not null primary key clustered)
               print 'table created'
          end 
go 

--------------------------------------------------------------------------------
-- drops the table
--------------------------------------------------------------------------------

if exists (
              select * 
              from sys.tables t
              inner join sys.schemas s
                      on t.schema_id = s.schema_id
              where t.name = 't1'
                and s.name ='dbo'
          ) 
          begin

              drop table dbo.t1
               print 'table dropped'
          end 
else
          begin

               create table dbo.t1 (i int not null primary key clustered)
               print 'table created'
          end 
go
