abap - 发送邮件，邮件正文带表格和excel附件

发送内容 的数据获取：

•  正文部分使用cl_document_bcs=>create_document静态方法实现
•  传入参数为html内表结构 

      CLEAR lo_document .
      lo_document =  cl_document_bcs=>create_document(
                      i_type =    'HTM'
                      i_text =     lt_html
                      i_length =  conlengths
                      i_subject = lv_subject ).

• 添加附件使用lo_document->add_attachment 
• 传入参数为二进制数据（Excel的制作使用ZXLSX_WORKBENCH方式，百度搜ZXLSX_WORKBENCH就可以了）

      CALL METHOD lo_document->add_attachment
        EXPORTING
          i_attachment_type    = 'BIN'
          i_attachment_subject = lv_att_subject
          i_attachment_size    = lv_att_size
          i_att_content_hex    = lt_doc_table.
