Hi, welcome on this forum where users try to help other users. You can help too, also by giving more infos about your system.
You need a bit knowledge of php. The model is prepared for such views. Best you make an template override and insert a new column for the view of a.maxplaces. Good luck

Thanks but,
which file i have to modify?

At first make a backup
you study how to make a template override for:
you copy site/com_jem/common/views/default_events_table.php to [YOUR_TEMPLATE]/html/com_jem/common/default_events_table.php.
Then you can work on this file
