How can I export a table from a function module

Hello friends,

I want to know how can I export an internal table from a function module, for example, in the export tab I want to have my table called IT_DATA

but for insert parameters in the export tab, I need have these objects in the ABAP DICTIONARY but I don't know how can I define this internal table into the ABAP DICTIONARY, is this possible?

And, If I want to export a table from a function module. ¿Where I have to define the table? in the EXPORT tab or in  TABLES tab?

Best regards,

Luis.
