Passing output parameter to an sp which accepts datatable as a parameter using dapper

Question

Hi I am working on mvc as part of my learning, So I came accross a situation where I have to pass a datatable to the sp, along with the datatable I have to give one output parameter of int also of the type. Currently I am using this code

con.Execute("XXXXXXX",
 new { @LoginId = LoginId, @City= City, @RegionCode = RegionCode, @CarList= Cars, @CompCOde = COmp},
 commandType: CommandType.StoredProcedure);

Here Cars is a datatable so I want to add an output parameter to this , please suggest me a solution.
