Template of concatenate internal table as excel attachment

There are too many articles that talk about excel attachments, no matter whether ABAP2XLS or using cl_salv_table->to_xml, etc. Sometimes no need to use a gun to shoot a mosquito when the gun & bullet are not ready.

Here is just one small code to quickly send one internal table as an excel file, which will be used as a template for myself. I would like to hide this blog if here provides this functionality. Please ignore this and sorry if it causes duplicated subjects& content…
