Transfer filed symbol to internal table in sap?

Hi Guys,

My requirement is to transfer the data of field symbol as a excel file via mail, so for that I want to convert first data of filed symbol to an internal table for further process on data but the issue is field symbol is of standard table type and I don't know how to create an dynamic internal table of that field symbol type.

The declaration of field symbol is mentioned below:
FIELD-SYMBOLS:<lt_pay_data> TYPE STANDARD TABLE.
