I'm not if I understand your concern completely. Do you want to add tour dates, venues and locations of a list of specific events on a table grid or chart? Please do provide us more details of your concern so that we can better assist you.
The following widget might be of a help:
Data Grid Widget - You can display a list of events with details using a grid like display.
Date Reservation Widget - Using this you can display a calender where users can do a reservation on a specific date.
Gift Registry Widget - You can also modify this widget to something selling a specific number of seats or tickets in an event.
I hope this helps. Let us know if you need more assistance on this.
