Exporting a sub-grid from the main form

Hi all,

    I have an entity called 'MIS Tickets' and want one field to be a multi-select  option set displaying different  QC ids related to one MIS Ticket.  I used a N:N relationship between QCs (a custom entity) and MIS Tickets.Then, I added a sub-grid on MIS Tickets with a lookup referencing QCs. Now, when I add data into MIS Tickets,  I want to be able to export the associated QC ids from the sub-grid viewable on the excel sheet. Understandably, I am unable to export the sub-grid because  it is impossible  to fit a table into a cell. But, is there some other way in which I can extract the QC ids , maybe separated by commas or semicolons onto my excel sheet successfully?
